Damn... I’d really like to see what they look like before I open mine up

the reflectors on the earlier lights are smooth, you can't just put a clear lens on them because they won't reflect light properly and will scatter it everywhere as the old style lens is what does the reflecting. If you want OEM housings you are better off buying used ones from ebay because every photo I have seen of aftermarket headlight housings shows horrible and erratic light output

Just for an update on the snow/ice.

I’ve drove a few days now in the white stuff. The lenses haven’t got covered while driving but also if they are covered when started they don’t melt off.

I am interested to know if an LED bulb in the high beam indicator would replace a high watt 6 ohm resistor to make it illuminate. That resistor is drawing just over 2a just to make a bulb light up.

Glad you like it as well. It's perfect for what I need.

I actually never noticed if my high-beam indicator turns on or not. I use my light bar instead of high beams when I need it.

true ….leds don't produce much heat up front

Can you use load resistor to produce enough heat under your headlight to melt it off?

I just wanted to throw this out there for anyone looking for a Plug and Play headlight relay harness. I came across this one from TacomaWorld, and it has amazing reviews, and appears to have much higher quality components than some of the more well known brands out there making these.

Headlight Services - Wiring

Looks like its heavier wire. Folks really have to watch what gauge of wire they use and how many amps they are pulling through the wire.

I rewired a 1968 GMC truck because its owner decided to put a high output alternator on stock wiring and melted the entire engine harness right out out of the truck.

That would be true if They didn’t have projectors

Just for kicks and giggles I looked up pricing on the components they claim to use (hey, we're DIYers, right?!!?) Looks to be the fairly typical 50/50 split of materials and labor, meaning you could head on over to Amazon and buy the raw materials for just a hint over $50... probably cheaper if you're less picky about brand names. Even if you have to buy a quality crimper, you're in for the same price and walk away with a tool.

I've made hundreds of these myself, motorcycles have crap for headlight wiring (and they used to run all that power through the damn handlebar switch!!). It's just about as simple of a circuit as you can make, plenty of diagrams out there that detail what's needed.

I haven't done it yet, but want to verify what was said earlier from Stern, that a harness doesn't really gain you much with these trucks. The link has good info on that at the top, above the chart that shows performance decrease based on voltage. I use the battery instead of the Alt (though have done the Alt before, after installing an adjustable regulator and kicking it up to the maximum/14.X) since the harness takes power off the battery, but checking Alt output is good too.

If you're doing a projector retro get the cheapest '99-'02 clear glass aftermarket lights and swap the lenses. I've seen photos on this forum of members who have done such a thing (projector retrofit in OEM '96-'98 headlight housings with newer lenses swapped over).

I didn't say that DS said the harness won't help (or if I did, I didn't mean to) - what he said was that he would put in new headlights first, and only do the harness if that didn't help enough. And he sells upgraded harnesses, so he could make money by pushing the harnesses. Here's part of our email discussion:

I too am looking to replace my current headlights on my ‘99. Was wondering if I should go the Halogen or LED route and was leaning towards the LED route. Does anyone have any suggestions?

Sorry for Stomping on your question, new to the group and won’t let me post my own thread.

Yeah, that's the picture i'm looking for, really want to see what they look like before I buy some clear lenses from Rock Auto(they are only $40 and glass). It's kinda hard to find a good price on the 99-02 lights.
