Gearhead Posted February 25, 2008 #1 Posted February 25, 2008 Do any of you guys have any experience with different LED drop-in bulb replacements for 1157's? I've read that many of them are less bright than the old incandescents. Any opinions on good ones out there for an 87 VR? Thanks, Jeremy
mother Posted February 25, 2008 #2 Posted February 25, 2008 save your money. a bunch of us on here have tried. the LED is not as bright, and the bulb failure light stays lit on the dash driving you nuts. try a 2357 bulb, yes i draws more current when braking but is much brighter.
Gearhead Posted February 27, 2008 Author #3 Posted February 27, 2008 Thanks for the input. My goal is not to improve the lighting, but to conserve electrical power with a minimum impact to lighting. I experimented with pulling bulbs out of my bike and this is what I found: the front running / turn lights aren't tied to the computer at all, so they don't trip the sensor. With the front bulb out, the rear blinks a bit faster but still OK to me. The rear are signal only; their intermittent use has very little impact on battery charge, so I will leave them alone. The tail lights (2 bulbs) are tied to the computer, but as long as one of them is good the computer is happy, so I only want to put an LED in one socket. Again, I don't care about the draw of the brake light because it's intermittent, it's the tail light draw I want to curtail. I won't be saving much. 7W x 3 bulbs (2 front running, 1 tail light) = 21W, divided by 12.7 = 1.7 amps. But when the whole system is only rated at 30 amps, every amp counts. I installed a pair of 55W (8.7 amps total) driving lights which I like very much, and the charging system seemed to keep up. Then I installed heated grips, about 3 amps total, and I am starting to have problems. Have to be very careful about how long I run the lights. So, if there are any LED's that are ALMOST as bright, I will be happy. Statistically, most accidents with other vehicles happen from the front, not the rear, and the rear of my VR is covered with reflectors that I'm told really light up at night with any light shining on them.
