L.E.D Lights

[Crayola]

I put in some 3157 Led Lights in my 2001, The blinkers now blink three times as fast as they should, I was told i need to switch my flasher fuse from thermal to electric but i cant find it, where is it on the blazer? or does it already have a electric flasher?

From thermal to electrical? something doesn't sound right there... they are electrical in the first place.. the only thing you can do to cause them to blink like they normally should will be to get an equalizer that you hook up to your signal harness. It makes it so the bulb will flash at a normal rate and your truck won't think that there's a burnt out bulb.

Im having the same problem..........My lights flash FAST!!!!!!

I always liked the fast blinker.....I ditched my leds but there are def other threads on here to correct the problem. I just dont recall exactly what you need but I think they part have it at radio shack. Good luck!

If they dont have the load resistors at radio shack check out superbrightleds.com. I just got mine yesterday and they work great. You hook one end to the turn signal wire, ground the other end and your done.

digital_xtreme, so your saying my flasher, right now is a electric one and not a thernal one?

[digital_xtreme]

i have no clue.. i've never even heard that comment about LED turn signals before... i know you have to have load equalizers hooked up to both your signal harness's so that they blink at a normal rate and also so that your blazer won't think it's just burnt out bulbs.

ok the normal lights have a LOAD to them and in the flasher there is a thermal strip that when closed "cold" will put power to the bulb when on it will draw amps from the batt and in turn will heat up the metal in the flasher it well then pop off the contact "shut of the lamp" then it will cool and return to the contact "lamp on! so it is an electric thermal switch "that is what you hear" (click click click) anywho the led's draw like 1/8 the amps of the normal lamp so it will not heat it up as much and the metal will return alot faster (fast blinker) that is why you nead a load resister on your wire as explained above

Hope this helps.

oh and an electric flasher has a digital timer in it that will flash the lamps at a set rate no mater what the load. and if I remember you can't hear the click (odd you always leave your blinker on ha ha)

Here's my story with l.e.d.s - the stock tail bulbs are 3057, i beleive, and so i looked all over for 3057 leds...no luck. so i just went to autozone and got 4 red APC chevy 3157 leds. plugged 2 of em in, they work. plugged the other 2 in, and then nothing. nothing at all. no brake lights, no turn signals, no interior lights, and i think no horn.

had to drive home with no brake lights, except for the 3rd brake light on top. turned out i somehow blew like 3 different fuses while testing the new leds. i haven't messed with them since then!
