Jst2fst Posted December 29, 2011 Report Share Posted December 29, 2011 I'm trying to put on some led's and and I have no idea what wattage resistor I need to use. I know I need 4 I looked at radio shack and saw some of the little ceramic ones and check around and was told either some 25-50 watt ones would do the job. Is this correct I really don't wanna have to but all sorts just to see whats gonna work out. Thanks Quote Link to comment Share on other sites More sharing options...
Simplysix Posted December 29, 2011 Report Share Posted December 29, 2011 You changing the fronts or the rears? Quote Link to comment Share on other sites More sharing options...

jblosser Posted December 29, 2011 Report Share Posted December 29, 2011 If he needs 4, I'm guessing front and back? @Jst2slow: you could always go with no-resistor-super-fast-blinky. Quote Link to comment Share on other sites More sharing options...

Simplysix Posted December 29, 2011 Report Share Posted December 29, 2011 If he needs 4, I'm guessing front and back? .I have heard of some people using 4 just on one end because of the heat resistors put off, so they will use two backtoback to help dissipate heat better.

Simplysix Posted December 29, 2011 Report Share Posted December 29, 2011 have you thought about using a aftermarket turn signal relay instead?http://www.customled.com/products/flasher_relay/flasher_relay.htmhttp://www.youtube.com/watch?v=1f8CxS9Cf9s 1 Quote Link to comment Share on other sites More sharing options...

I'll check them out Quote Link to comment Share on other sites More sharing options...
magley64 Posted December 29, 2011 Report Share Posted December 29, 2011 check the resistance of the stock bulbs using a multimeter... then use a resistor with that value for each? Quote Link to comment Share on other sites More sharing options...

Cme2c Posted December 29, 2011 Report Share Posted December 29, 2011 If your bike uses a flasher relay (some have it programmed into the bike's ECM), just pull out the flasher & see if it is a 2 or 3 prong flasher. Take it to Autozone and get a new one that says it's led compatible (they're in the same isle as the replacement bulbs). I just did that for my daughter's Buell & it works fine & only cost like $15.

Cheech Posted December 29, 2011 Report Share Posted December 29, 2011 check the resistance of the stock bulbs using a multimeter... then use a resistor with that value for each?ding!If you do end up going with a ceramic resistor, make sure that puppy isn't touching anything fragile like other wires. They will put out some heat, especially if you forget to turn your turn-signals off like I do sometimes. Quote Link to comment Share on other sites More sharing options...

I just did that for my daughter's Buell & it works fine & only cost like $15.Yeah, this will work, too... these flashers use a IC timer instead of a current (heat, pop, reset) timer for the flash cycle.When I wired up my turn signals in the dune buggy, (all LED) I used one of those strobe controllers to control the flash speed. It's pretty cool cause it's adjustable on the fly, and I can switch from single to triple flash...I suppose I could've programmed my own timer, too using a pic microcontroller...or built a wigwag using a couple capacitors and a couple resistors. But that seemed like a lot of work. Edited December 29, 2011 by magley64 Quote Link to comment Share on other sites More sharing options...

RSparky Posted January 5, 2012 Report Share Posted January 5, 2012 I saw an led kit with two 6 ohm resistors... One per side. Should work for most led set ups. Quote Link to comment Share on other sites More sharing options...
