    Reason for replacing standard bulb with LED bulbs

    What is the reason some of you change your standard taillight, brake or turn signal bulbs with LED bulbs?

    The cheapest thing on a BMW is the nut that connects the handlebars to the seat.

    Generally LED are brighter, last longer and draw less power.

    I can agree with the brighter and last longer but the draw less power is only true if you don't put the parallel resistors across them to make the flasher and bulb monitoring circuits work correctly. If you add the resistors you're just negating the less power reason.

    I also like the way they turn on and off more sharply.

    I've replaced my standard tail light with a multi-unit LED one. Much more visible when I stomp on the brakes now.

    I put LED light on my pull behind trailer because ever since I bought the trailer I though that the lights were very poor, especially in daylight. The original light fixture had a single dual filament bulb and no reflector. I often had trouble with them working at all unless I took them out, sanded and sprayed WD40 on them. The LED setup that I bought were shaped the same so they are a direct replacement. They also have multiple LED scattered across the surface. I'm much happier with them now.

    True on for turn signals. Brake lights, running and dash bulbs draw less power. For some bikes with small alternator led bulbs can be a huge power draw saver allowing for the use of heated gear when otherwise you couldn't.

    It's why I said generally.

    Does having a Signal Minder also remove the need for the resistor modification?
