HELP ! These 11W High Power LEDs Burnt My Fuse Twice!

kashahyah · 08-07-2009

Just tinted my rear lights. I bought these LEDs cuz my friend said they're BRIGHT so they can makeup the brightness loss for the dark tint. I got them today, I put them on and turn up the lights. They blinked once and then dead. And I cannot hear the turning signal click sound anymore. I went check the fuses, they've burnt my 10A fuse. I

and put on a backup 15A fuse and it also got burnt. WTF ?!

Don't want to try 20A fuse since it might harm the rest of the circuit.

Should I return those LEDs or I need some mod ?

You need to replace your flashing relay. Its burnt out. You can order flasher relays online that are designed to flash at a constant rate instead of at a load rate.LEDS draw very little current so they dont provide the necessary load to cycle the flasher. You burnt out your relay with those LED bulbs thats why its popping fuses. If you cant find a relay designed for LEDs you can use a 10w 10 Ohm L-Pad (sandstone resistor) wire one across the - and + terminals of each light to provide the necessary resistance load to make a normal flasher cycle. Either way you need to replace the flasher before you put another fuse in.

so when you engage the blinker there is no light on the dash and no sound? if so i dont think you have to replace the flashing relay. if the light is burnt or if you have burned the fuse then you wont get any dash lights and no sound either, it happened to me in my civic as well. however i have no idea why they would burn out just because of the bulb. maybe its the wrong bulb?

led bulbs should not burn your relay, unless the leds suck (which is very possible since almost all those junk bulbs are made overseas). i have a LED flasher relay in mine even tho i dont have led signals YET. you can buy the one from auto stores made by tridon (same as oem brand) and its EP_34 i believe for the part number. it should say LED somewhere on the flasher. ive tried it and sure enough, the led bulb blinks at a normal speed with this flasher.
