LED HEADLIGHT BULB ISSUES!!!

[Poston]

I recently purchased a set of rs racing g2 led headlight bulbs for my 14 silverado. They took a while to install and work great with the truck off. As soon as I start the truck they go off and will not come back on until it's turned off and the key is reset. I've noticed that some of you guys with hid headlights have had a similar issue and used something called error cancellors, is this my issue? Any help or info would be greatly appreciated! Thanks

It's got to do with the drl. If the truck is off, the headlights are powered like they are when the switch is in the on position. When you turn it on, it defaults to drl mode which is pwm. Which is no Bueno for leds.

Any idea if the error cancellors will work? There has to be some way to fix it. I hope anyway.

What does "PWM" mean?

I'm trying hard to find some LED headlights for mine too. If you hear of a fix for the problem I'd really appreciate a heads up.

 

Thanks,

What does "PWM" mean?

PWM is pulse-width modulation. Basically to run your normal halogen headlights in a "low power" drl mode, it sends pulses of current to the headlight instead of a constant one. This essentially only powers the light in pulses (though be it extremely fast and unnoticeable in halogens). Since halogens take time to heat up to full brightness, this is basically heating then letting the filiment cool in microseconds and not allowing to to reach full brightness. What this means to HIDS and Leds is that they need a constant current to sustain an arc of plasma (in HIDS) and a constant voltage to power an led chip. This can be solved with a capacitor which is essentially a short term battery. It gathers the pulses of energy and releases them in a constant flow. Hope this helps, kinda long winded. Sorry

This link is to an explanation even I can understand. Constant voltage, with a controlled pulse that varies in duration. http://arduino.cc/en/Tutorial/PWM

I don't have a clue what it means but "thanks" anyhow .

Thanks!! Where could I get the capacitor you mentioned and how would I install it to make the LED headlights work properly?

Ok guys I got them working and without a capacitor. I bought an hid wiring harness kit that uses a relay that controls both LED light bulbs off of one. In other words it uses one plug that would normally plug into the back of a regular h11 bulb to tell the relay when to turn on and off and the relay gets power straight from the battery and sends a non pulsing flow of current through the harness that has 2 other plugs that plug into the ballasts, works like a charm.

Glad to hear this worked for you. In the future though, if you start getting a buzzing sound from the relay in your harness or flickering in the lights then you will need the capacitor. This is because the PWM is causing the relay to trigger off and on. If you do get this then simply plug the capacitor in between your harness and the plug you used to plug into your stock headlight. Should fix it.

Without the capacitor the relay is likely still turning on and off and that will destroy them quick, so your better off just paying the $5 for one now. You will only need on since you have a single side connection.
