LED Headlight bulbs as DRLs?

[romad]

I know the DRL circuit runs the stock incandescent headlight bulbs at a lower voltage to act as DRLs. But I was wondering if the stock bulbs were replaced with LED bulbs, would the DRL circuit still work? Also, would the lower DRL voltage damage the LED bulb circuitry?

I rewired the DRL circuit to power a pair of LED driving lights (instead of the headlamps). They work just fine. So I'm assuming LED headlamps would work as well.

One weird thing I noticed: When turning the key (with the parking brake engaged), the LED lights will blink, just briefly. I think it's a combination of how the circuit is designed, and how quickly LEDs light up. The parking brake relay (which is normally closed) takes a split second to energize and open the circuit. During that split second, it's sending power through the circuit. So you get a brief flash from the LEDs. I don't really care. But at night, it sometimes startles passersby.

Run a relay on that to the battery. You wont damage LEDs with less volts, only more.
