what resistor? electricals, helps me out
so, im doing some custom light work, and i got a led sequential integrated taillight. only problem is the signals dont light up sequentially unless i use two resistors (see pic). problem with that is
1) the light only came with two resistors, and i would need four, two per side. 2) they get hot, and so i hear, burn out frequently. solution-get one resistor that has a rating equal to the two resistors. or something else you guys come up with... id guess since i need two 20w 5ohm resistors per side, one 2.5ohm resistor would do the trick, but does the wattage stay the same? ive read that a no load flasher slows down the led blinkers, but where is it wired? inline with each side? or its a replacement for the flasher relay in the harness somewhere?

Do you have LEDs on the front as well?
3 ohm 50w is a pretty typical power resistor. Just get two of those. What kind of bike is it? They sell LED flasher relays for pretty cheap now that have OEM connectors so you can skip wiring. Such as this one: http://www.customled.com/products/fl...sher_relay.htm

if you don't lube the konutter valve, you are screwed.

Tridon EL13 is a common electronic ('no-load') flasher available at pretty much any parts store. Way better solution (and cheaper, unless using the shitty ceramic radio shack ones) than installing 'load' resistors (heater elements - prone to failure & a kludge solution).
Just replace the OE flasher relay w/ it. Only caveat is needing to crimp generic spade-terminals on the wiring harness after identifying ground, + in & + out (+ in/out may not matter, don't recall). Last edited by Kerry_129; 03-24-2011 at 05:16 PM.. |

found out my flasher is all in one unit with two other relays-too much work to get to the wires that go to the flasher part and then splice into the harness.
radio shack sucks, had nothing i ended up going with two more for a total of four, since the one electronics place that shouldve had it only had up to 25w in 2,3,4 ohm. built a box out of sheetmetal(doubles as heatsink) mounted it to subframe, soldered everything together, works good....cept my front blinkers are much dimmer and i lost the fast blinking, which i liked. slightly dimmer with one resistor, noticeably dimmer with the two. so im going to try a 25w 2ohm or 3ohm, since it was so easy to do and they cost $1.50. the rear taillight looks really cool tho. nice and bright electronics store - $1.50 and theyre called resistors. Auto parts store - $9.99 and theyre called load equalizers id upload the pics but i cant find my camera's usb cable.

its a 2000 gsxr 750
leds on the front too, but with the last integrated tail i had, didnt need a resistor or anything. this one i do. ill check out the flasher

First off the drawing you have there shows the resistors in parallel. If they were in series I would say they are 10Ohm and you need a 10 ohm....
however, having forgot the formula for parallel resistors (somethin bout inversion...i'm sick and don't have all my facilities but if you were to get say one a 7 ohm you may have the issue licked. just remember when you are in parallel like that they aren't actually that strong and that also may be causing your heat issue. Get a circuitry for dummies book that will help.
