Has anyone changed the front turn signals to LED bulbs?
If so, what bulbs did you use and did you have to change the flasher or add a resister in line for them to work.

I haven't changed them yet, but I do know you need to add a resistor in the line for them to work.

I don't know if there is an indicator on the dash that tells you when your lights are out though.

I've been told to use the flasher instead of resistor, The whole point of using LED's is to use less energy.If that is the case,then the replacement flasher will do that.The resistor,won't .

Apologies for the intrusion, but I would like to offer my advice as an electrical engineer regarding LEDs replacement.

(1) Some LEDs replacements will offer reduced energy consumption. However, the signal lights use an insignificant amount of power when compare to the rest of the electrical systems in the vehicle and for the amount of time they are used.

(2) The reason the LEDs may need a resistor is because an LED does not works like a regular incandescent lamp works. An LED is made out of a semiconductor material and it requires a certain bias current. Having a resistor in series set such bias current and therefore allows for appropriate operation of the LED.

(3) Don't get discourage from pint (1) above. LEDs does look great and they will create a different appeal to the look of the car. Choosing the right replacement LED lamp will do it.

(4) Finally some LED lamps require to be installed in the correct polarity. That is + terminal and - terminal can not be reversed, otherwise the LED will not work or much worst it can be damaged.

Wow Electrol, very good explanation. We ( l ) always appreciate the vast amount of technical experience on the board. I know I do! ;-)
