Question:

Hello, I have a 1975 Trillium. The rear brake/signal bulb is 2057. Can I replace it with a 2057 compatible LED bulb. I have read a few posts that says I need a resistor to make it work properly??? Sincerely, Peter

Hey Peter! If you can find an LED compatible 2057 bulb then yes you can replace it but we do not have one so sorry I can not help you there.

As far as adding a resistor goes, maybe? You may not need load resistors when you switch to LED bulbs. The best thing to do is to try the lights without load resistors first and see if you have any issues.

If you experience hyperflash on the turn signals or the LED lights do not have enough draw then you'll want to add one per circuit using the Load Resistor Kit for LED Turn Signals item # DI34ZR.
