I dont actually think this bulb exists, I cant find any other bulbs on my CT200h. It may be that this is also the front turn signal and they just listed it twice for some strange reason.

I have installed everything except the turn signals and headlights.

If found out what the A and NA mean.
A = Amber painted glass (cheaper to make)
NA= Natural Amber glass (glass is made with the amber color)

Also, I dont think the parking light listed above even exists.
The only lights I see on the front housing of the car are the high headlight H9, low headlight H11, drl leds, side yellow marker light led, and the 7444NA turn signal. There are no other bulbs.

(this is so you dont scratch anything while prying, also used to remove your side mirrors for the puddle lights)
-----------------------------------------------------------------------------------------
Backup lights - 194 LEDs (outer lights) and License plate lights - 168 LEDs (inner lights)

1. Just pry open the 4 access hatches on the cargo door.
2. Rotate the bulb socket to the left to pull out the bulb socket. (the license plate lights have a very tight fit, may hands barely fit, if you have big basketball player hands you may not be able to read them.)
3. Install the LED bulb into the socket.
4. Check that at the bulbs work and swap their directions if needed. (the LED bulbs only work one direction due to the polarity).
5. After verifying all the LEDs work, reinsert the socket into the housing and rotate it to the right to lock it in place.
6. Reinstall the 4 access hatches.
Less than 10 minute job.
-----------------------------------------------------------------------------------------
Cargo Light - 3022 LED

1. Use the plastic pry tool to pry open the housing.
2. This LED bulb is slightly longer than the original bulb. You will need to bend the tabs to get the new LED to fit properly.
3. Install the LED bulb.
4. Check that it is working. If not then reverse the bulb.
5. After verifying it works, the push the housing back into place.
-----------------------------------------------------------------------------------------
Dome Light - 3022 LED

1. Use the plastic pry tool to open the dome housing at the notch. Just pry it open.
2. This bulb is a little longer so you need to bend the tabs to get the new bulb in.
3. Check the bulb works and reverse it if it does not.
4. After verifying the bulb works, push the cover back on.
-----------------------------------------------------------------------------------------
Map Lights - 168 LED

1. Use the plastic pry tool to open the cover by prying from the windshield side.
2. It is hard to grip the old bulbs to remove. I wrapped a rubber charity bracelet around the bubs, tightened it, and then pulled down and the bulbs came right out. Also a rubber band would probably work to do this.
3. Install the new bulbs.
4. Verify they work and reverse the bulb if needed.
5. After verifying the work the push back on the cover.
-----------------------------------------------------------------------------------------
Visor/Courtesy Lights - 168 LED

1. Use the plastic pry tool to open the cover. I pried from the left side.
2. Swap the bulbs.
3. Verify the bulb works and swap it around if needed. (for those who dont know how to turn this on, you just slide the visor mirror cover over and it switches on the light).
4. Reinstall the cover.

------------------------------------------------------------------------------

I bought the turn signals and when I get them I will make a new topic to install.
I could not find the parking light listed above and I dont think it actually exists. I think they just listed the front signal twice as the parking light.
Here are the only bulbs I could find:

This is a great resource, thanks for this. So basically, anything that was currently LED on the car you left as is, you only converted over anything that was halogen to an LED??

Yes, I am only changing the halogens to LED. Stock LEDs will be untouched.

I bought some generic china LED headlight bulbs, but I have not received it yet to see if it is bright enough to replace the stock halogens. The OEM LED headlights are like $1,700 a piece so that is not worth buying.
I have not bought the turn signal LED bulbs yet either, but I did buy a new flasher relay that is needed for the lower wattage LED turn signals.
Amazon.com: 8-Pin 81980-50030 066500-4650 Electronic LED Flasher Assy Relay Fix For Lexus Scion or Toyota LED Turn Signal Light Bulbs: Automotive


All that i have left to do is the headlights and turn signals.
The only halogen lights you cant get rid of are the high beam lights. Even on the OEM LED headlight the lows are LED and the highs are still halogen.
I guess no one makes an LED bright enough for your brights.

How do the LEDs from Velocity Shop look? They are down the street from me and i was looking at the kit you got.

Also, how do you change out the poodle (puddle) bulbs?

They are basically the same brightness as the stock halogen, but instead of yellowish they are daylight/white color.
The 168s from velocity shop are the same as the ones from superbrightled, but the velocity shop is cheaper for the kit than buying the individual bulbs from superbrightled.
They are 5050 SMD LEDs. The Velocity shop kit is short QTY 4 of the 168 bulbs to be a complete kit. They are missing 2 for the puddle lights and 2 for the visor/courtesy lights. If you go to their store ask for 4 more of the 168 bulbs so you can change all of them. Superbrightled sells them for $6 each so dont pay more than that from velocity shop for the extras.
The only way to get brighter is to get oversized bulbs with more LEDs on them. I would say that in each housing you could fit any bulb that was double the length of the standard size.

The only issue is the 3022 LEDs are longer than the stock halogen cargo and dome lights, so you need to bend the metal tabs to make it fit. It will fit once you bend the tabs. I dont know if you can get an LED to the correct size which is why they probably sell the 3022 size.

The mirror/puddles lights are easily changed, see here: http://www.ct200hforum.com/forum/lexus-ct200h-how-do-yourself/131186-install-mirror-puddle-led-lights.html

If your not going to pay $1700 for the factory led headlamps, don't even bother with putting your own bulb in there to replace the halogen bulb. No they are not brighter and no they won't have the same light output. Trust me on this. They will be for show only and greatly impair the use of your low beams. There is not an LED headlamp bulb made that can give you light output equal to or greater than the halogen. I have a cree LED bulb in my fogs and they work great for that only. There is a reason why the factory led headlamps have 2 projector bulbs per housing.

So you tried the same bulbs I plan to try and you know for a fact that they dont work or are you just fear mongering?
I bought LEDs to use as headlights and when I get them I will test to see if they work.
On paper, if their lumens spec is not a lie, they will be brighter than the stock halogens. If the chinese lie then it wont work, but I will give it a try before knocking the idea.

Only someone crazy would spend $3,400 on LED headlights when that does not even include LED brights.

As a matter of fact they don't make an LED bulb that projects enough light for a headlamp, period. I know a thing or two. The lumens have nothing to do with how well it projects light. The problem with LED bulbs is that they don't project. That's why the look bright when looking at them, even brighter than halogens. However once you get behind the wheel it's a whole different story. I got top of the line LED bulbs with cree chips and built in projector housings for my fogs, they are WAY brighter than the stock fog light bulbs but light output on the road is less than the stock bulbs even though the lumens are greater.
I'm just trying to warn you but if you come back saying they are equal to or greater than the stock halogen bulbs then I know you're lying. Like a said before there us a reason why the stock CT LED bulbs have two projectors per housing and the new Lexus RC's have 4 or more per housing. If Lexus could pull off one LED projector to get the light output that's needed they would do so. Some cheap Chinese bulb is not going to solve that problem.

In the end you may be right, but really you are just guessing. New LEDs come out all the time and it does not sound like you tested anything but LEDs in your fogs.
The LEDs will disperse light differently than the halogen as they are directional and not omnidirectional, so yes even if brighter they may not work in the stock housing as it may not reflect/focus the light properly for the LED orientation.
I say it is worth trying and to document it the results showing if they work or why they dont work.
If you want to try it out, provide pictures, and describe why they dont work then go for it. Posts just being negative with nothing to back it up are pointless.

I searched, there is very little data from people showing the results of their testing. People want to see data, not just hearsay.
To me it is worth trying and then documenting the results so others know if it will or wont work.
Also you never know when a new designed LED will come out that could work.

Coincidentally the LEDs arrived today.
I took some pictures in a field, but I accidentally had the fogs on so I need to redo it.
I think these will be just as good as the halogen stocks, but white instead of yellow.

I will take some better pictures this weekend on like the darkest road I can find with both the halogens and LEDs.

I hate the plate bulbs to damn hard to turn and get out not enough room to get new led in and easily turn. Any tips for getting them back in? I gave up for tonight

Dude. You have no idea. I had the brilliant idea to replace the interior bulbs yesterday and then decided "might as well do the plate bulbs"... but I'm in Chicago and it was 3 degrees outside.
I got them in, but couldn't feel my hands afterwards.

I have a pair of needle nose pliers that I've wrapped with PTFE tape, so it doesn't mark up the plastic. I unplug the harness and remove the bulb holder with the pliers. After changing the bulb, I reconnect the harness (to prevent losing it in the hatch) and get the holder back in place and twisted just enough so it holds. Then I disconnect the harness and lock it back in with the pliers. The passenger side went in pretty easily, but the driver's side took about ten minutes to get back in (but I'm chalking that up to loss of dexterity due to the cold)

So I replaced the two map lights, rear dome light, hatch light and plate lights yesterday. Still need to do the two vanity lights and the puddles.
My HIDs are arriving today and I got some new bulbs for the fogs, so I might try to finish that up this weekend. I'll post pics.

ya having pliers help with getting them out, but putting them back in and turning them to lock them in place will likely require your own fingers.

i just tried putting in the reverse lights with a 68SMD LED but my question is: will replacing the reverse lights with LED make it brighter than the stock halogen? i guess i can go bigger than 68SMD and see but it seems like its still not as bright as the stock halogen...i will wait til its dark and see the results outside

left is white LED, right is stock halogens





not sure why my camera is making it blue-ish, but the LED is white to the human eye

If you haven't installed them yet, do you mind putting up side-by-side pics like chroma23 did? I picked up these, but if they are brighter than mine I might pick them up because I smoke tinted my tail lights and I want to have the reverse lights as bright as possible. Thanks.
