    Hi friends!

    Brutus the Nitro is alive and kicking. Will hit 220,000 miles this weekend!

    I'm looking to replace the bulbs in my tail lights with LEDs. If at all possible I'd like to do it without installing a resistor. The folks at superbrightleds recommended to try these bust said I might still need to install one.

    Has anyone had success with installing LEDs without needing to install a resistor?

    Thanks for any help!

    I've got led's in my tail lights, they work fine without resistor except for the turn signal.
    You want get arround resistors there.

    How did you have those resistors wired up I tried to install my LEDS with resistors but my turn signal no longer worked as in no flash was made they just stayed lit

    I didn't. I'm still on it. there are bypass decoders or use the following formula:
    for example if the led has 7 watts then the difference to the 27 watt bulb, is 20 watt. 20 watt divided by 12 volt is 1,66 ampere. 12 volt divided by 1,66 ampere = 7,6 Ohm

    Thank You Gio for your reply and Okay so instead of the load resistors buy the bypass decoders’?

    For turn sinals wire load resistor in parallel. Not needed for brakes.

    So, really, I could convert all bulbs to LED except for the turn signals and not experience any issues?
