Greetings!
I'm looking for a recommendation on LED turn signal bulbs for the CT. We have a 2016. I found another thread on a similar topic, but one thing that didn't seem clear was whether the flasher relay still exists on certain years, or if it was replaced/integrated into the instrument cluster, like on a lot of other cars.
Our car does NOT have the feature where you press the signal stalk partway to make it blink 3 times. (I personally HATE that "feature.") If you press it partway, it blinks as long as you hold it.
I purchased some 7440/7444 bulbs with built-in resistors on eBay. They mostly work, but I've found that, at least in the front, if the signal is blinking for more than about a minute (e.g. at a long traffic light), it will start to hyperflash. I'm guessing that maybe as the bulb heats up, the internal resistors don't create as much resistance, so the car thinks a bulb is burned out and hyperflashes.
One thing that's kind of weird on this car is that the rear signals use 7440, while the front use 7444. The 7444s have 2 filaments, but these bulbs do not light up when the parking lights are on; they function ONLY as turn signals. So I'm unsure why Lexus made them 7444s, vs. 7440s. I did notice that incandescent 7444 and 7440s are slightly different in that, aside from the 7444 having 4 contacts instead of 2, there is a small protrusion on a 7440 bulb that will prevent it from plugging into a 7444 socket.
So, my questions are: 1) Does the 2016 have a flasher relay that can be replaced? (If so, I know it's not easy to do based on the other post I found for 2011-2014.) Or, if not, then 2) Is there a specific LED bulb with built-in resistors that anyone can recommend?
Thanks!
