1.yes.don't forget to inspect/repair the headlight switch harness.
2.i didn't need any silicone on either of my sets.well sealed.the depot lights may be cheap,but well sealed you can say about them.the most lacking aspect of them is their hardware.the more of the oem mounting clips/screws you can use,the better.
3.i never did that part.didn't need any extra light after new lenses and relays.

 

Great, thanks!

 

The only issue that I had with DEPO lights is that on really humid days, only the corner lights would get moisture inside. I've never had any problems with the turn signals or headlights.

All I had to do was put a small bead of silicone on the marked areas on these pics.

 

Great, thanks for the pics! I'm sticking with the OEM side marker and turn signals.

Was concerned about the DEPO headlights getting condensation. Glad to hear that they are sealed well from factory and no silicone is needed.

 

questions....

I removed my drivers side headlight assembly. After unplugging the headlight plug I found the 3 wires, red, green, and black.

However, I don't see where the black is grounded in back of headlight bucket as suggested in the how to article? All 3 wires go into in a larger loom and the black wire doesn't appear to exit to a ground.

1. Where is this ground?
2. Also, the new headlight plug I purchased has 3 wires...all black. How do I know which one is high, low, and ground?

Thanks

 

This might help.

The ground exits the harness by the passenger side light and grounds to a screw that goes into the core support right in front of the battery. Double up on the grounds every chance you get!

 

Thanks Eaker!

Now....

1. Do I ground the each headlight plug to a suitable ground inside the engine compartment somewhere?

2. I understand now that the oem ground exits loom at passenger side and grounds at post near battery. If I cut the ground at drivers side, what will I do with the end that goes into loom and the end from the plug? Connect them together?

3. I am using 2 Bussman type fuse holders with 20 amp fuses (1 for high beam relay and one for low beam relay)...will these be OK instead of a fuse block? My relays are rated at 40 amps.

Thanks

 

You can find a suitable place to ground it and then run an extra ground wire from that place back to the battery and then tie the old and new ground wires all together. That way if one ground gets a little bad there are plenty on others to pick up the slack. Remember, you cannot have too many good grounds.
20 amp fuses will be fine. I think 15 amp is what they run off of in the factory setup. You won't be drawing as much amperage as the original setup because you have separated hi from lo so realistically 15 amp per relay would be more than enough, but I always go just a tad more but not so much as to burn the wires before the fuse blows.
