Advice HID kit

#25
I just got my parts from ebay, ordered the housings and led bulbs. My question is about the plugs on them... high beams only have two prongs vs three for low beams. Do I need to buy specific leds for the highs? If so, please point me in the right direction. Thanks!

You can cut the top prong off or just bend it over so you only use the high beam.

If they are H4 LED's you will need to swap the top and right side terminals on the factory low beam plug.

As you look at the end of the factory plug/ socket, the left is ground, the top is low beam and the right is high beam.

Insert a small straight blade screwdriver in the front of the plug to depress the retention tab and pull the terminal out the back.
Bend the retention tab back before re-inserting.

Your welcome.
I had to do the same thing in the early '90's when I got some sample Hella H4 housings (4) and used H4 halogens for all four lights.
I bent the top prongs over so if the low beams burned out I could bend the prong back and swap bulbs from low to high.

I didn't realize Hella made high beam housings that took H1 bulbs until recently.

Be careful using the stock harness with some super bright bulbs. There's no relay on the factory wiring and it's not hard to smoke the headlight switch when you start running major current through it.


Not only is it expensive, but it'll fail when you're using it.


....at night

while most likely driving fast. :)

LEDs draw less power than halogen

is there a "hot wire" harness for the headlights?
Dennis Kirban sells one.

He calls it an upgraded harness because it gets power directly from the battery, where as the "hot wire" systems get power from the back of the alternator.

It says it won't work with HID's, but I suspect that's because the HID's (and LED's as well) use an H4 based light socket which is the same shape as the H4652 (low beam) but will need to be re-pinned.

Summary: use as is for H4652 sealed beams or re-pin the low beam socket for HID and LED.

The high beam socket will be ok.
