i read some where that said "when installing bulbs, use silicone dielectric grease on bulb pins. what do you say about that?

 

It would not be a bad idea, it would prevent corrosion.

 

I have never done it and never had a problem. Maybe you can try it but just as preventive maintenence.

This is an excellent idea. Expecially to those who run with higher wattage headlight bulbs. The melting wiring harness is caused by heat, and the heat comes from bad connections, not the bulbs themselves. Poor connections have resistance. Resistance + current = heat. Excessive heat = melt downs!!!! Keeping the connections in your light sockets and plugs clean is a major part of preventing meltdowns when upgrading your headlight system. Every one of the electrical connectors on my old Hon-Duh was packed with white grease. I never had a failure running higher wattage bulbs. I ran 80/100 bulbs on my Maxima for over a year and never had a socket show signs of heat buildup. I also treated the sockets with WD40 every time I played with them. WD40 keeps out water and corrosion thus keeping everything clean, neat and in good working order!

 

So are u guys saying that WD-40 will help to stop the harness from burning out?

 

Try and read the 1st post. "silicone dielectric grease"

Using wd-40 in an electrical connection is a bad idea. Water would be a better idea.

So the answer is a bigNO

 

If you ever drown a car with a distributor you can use WD-40 to get the water out of the cap to get the car running again (WD stands for water displacement) but using it for this wont really help too much. When njmaxseltd said bad connections create heat he was right but when you increase the wattage of the bulbs by 30 watts (55 to 85 watts) you have increased the current by 2.5 amps each. The added current going through the factory harness is going to cause the wire to melt the insulation eventually even if all the connections are perfectly clean.

 

The small gauge wires play into the meltdowns too though. There's not enough room for all that current to go but up in smoke.

 

Cheech and Chong!!

 

I think I shouldn't have said "Smoke".
