    Destroying Led's

    I have swaped out all of the bulbs on my V and I seem to be burning out the Driver side tail lights (only half of the led will light up when i supply 12 v)

    I dont have any problems when I install a glass bulb

    Try installing a resistor. LEDs draw less current and it may be the system thinks a bulb is out. You can find resistors all over the place, but I bought mine from V-LEDS.

    How do you like them btw? (other than the burning out of course)

    Riverside is my hometown, I'm curious how they look.

    I have a resistor on my turn signal and that got destroyed as well....Plus its only happening on one side of the car.

    I havent had any issues with my LEDs, i installed them on the brake lights/ runnin lights as well as reverse..Not to mention the License place and side markers as well...

    I havent had any failures as of yet...

    Check the fuses, and the voltage comin off that line, you may have a spike causing them to burn out.

    Its getting the right voltage (that was the first thing i checked) i've thought of changing out the fuse to a smaller one and see if that has an affect (its starting to get a bit of $$)

    Re: Destroying Led's

    You guys with the L E D's. Does your turn signal flash at a different rate ? & I thought a different relay was necessary.

    Since, amps = volts/resistance and L E D s have less resistance, would not there be an amperage increase with 12v applied causing the burn out problem?

    What is the wattage of the L E D. Volts X Amps = Watts

    The fuse isn't the issue. You need the proper current limiting resistor to protect teh LEDs.
