    Hi,

    I've done nothing to modify the lights on my gauges. But I did replace all of the turn signals bulbs and tail light bulb with units from superbrightleds.com. I replaced my stock turn signal flasher relay with an off-the-shelf generic unit. The stock flasher unit needs to "see" a specific load in order to operate properly. The LED bulbs do not offer enough load.

    Turn Signal Relay Replacement

    Bulb tests:
    This little video compares the stock Stanley 1073 incandescent turn signal bulb against a product from www.superbrightleds.com, their part number 1156-A45-T....

    One of my buddies wanted to see the dispersal pattern of the 42 SMD LED tower bulb and compare it to the bulbs in the first LED comparison video. As you can ...

    I like the way the 42 SMD LED bulbs fill the lens but these cheap ones just aren't as bright as the other two bulbs, the Stanley 1073 and the Luxeon 3 watt L...

    Here I compare the Luxeon 3 watt LED 1156 style bulbs with the stock Stanley 1073 incandescent bulbs. Personally, I think these LED bulbs are just as bright,...



    Thank you for your indulgence,

      That's all you need to drop the 12v to 3.5 needed for the led's.
      Unless you get LEDs that are designed to be used in vehicles. Then, the resistor is already built in, all you have to do is remove your stock bulb and insert the LED replacement.

      True, but ...

      If your bike has self-cancelling turn signals, installing ANY flasher other than stock will eliminate that feature. If you wish to use LED 'bulbs' and retain your stock flasher, you will need to use load-compensating resistors, but they will not provide any of the energy saving advantages of LEDs.

      True, there are differences in 'brightness', but viewing angle is also important. Some LEDs will be intensely bright, but only when viewed directly on-axis. Move sideways a few degrees, you will barely be able to tell that they are on.

      Also, when putting LEDs behind colored lenses, match the colors. DO NOT use white LEDs behind amber or red lenses, they will be incredibly DIM. Use amber or red LEDs. One exception is that a red LED works decently well behind an amber lens.

      As previously mentioned, if you buy LED 'bulbs' that are designed for a car, they are 'plug and play', no resistors needed.

      NOW you finally mention it.

        Thanks everyone! That clears up my doubts and questions - now I just need to hunt down some bulbs =]

        My stock turn relay is cooked so I guess I'll go with an LED relay for the new bulbs rather than the generic "thermal" relay I have now.

        I'll look into the LED's for the dash and gauges some more... I'm seriously considering going with red LED's for the gauges... maybe.

        Great info here, I really appreciate it!
