Flasher Relay

I installed new tail lights and put L.E.D bulbs in. Long story short, I found out that I need to put a new relay in to fix my fast flashing. Went to put the new LED relay in and all I get is chatter/buzz now. Is the new relay shot?

Do the lights have resistors on the LED bulbs if not that is most likely your problem

No resistors but from what I've read a new LED flasher will fix the problem without having to use them. Im thinking the new relay isn't good because of the buzzing it makes once I plug it in.

I think SKRWZ is on the right track. Even though it's an "electronic" flasher, going by the bottom diagram on your e-bay link, it probably still needs some resistance in the circuit to operate properly. An LED by itself basically looks like a dead short to the circuit. It has no internal current-limiting, so you may need to add some resistors in series.

I've never used those LED flasher's so I cant say but I have used resistors in the past with great success


check out this place for LED's flashers, and resistors good guy to deal with http://www.superbrightleds.com/cgi-b...rake-turn.html

Usually if it's a good led flasher you wont need to add a resistor to the circuit. I know lots of guys that build their own led lighting that don't use resistors. Just a led flasher.

Might be the pinout doesn't match the vehicle and it's being wired wrong.

Yeah, but on this one, if you look at the schematic on the ebay link, it looks like it assumes the LEDs each have a resistor. Not clear if this is mandatory for this unit, but I'd assume it is.

Easiest way to find out is splice in a resistor and see if it works.

I didnt use the one from the ebay link. Just showing you guys what I mean. Also what do you think cause the buzz/chatter I'm getting from the new one being plugged in? As for resistors I rerally dont want to be bothered with them. Thanks for the SKRWZ.

Where is the relay flasher in the 97-03. I can't find the old to put the new in.



Really? Its the Internet take it easy.

Underneath the dash and right of the steering column (pretty much behind radio and down) Its a black box. I had the flashers going to make it easier to find.

Just a heads up, its a bitch to get at, especially being 6'4 290.
