It is usually a combination of heat from the light itself being transferred to the wiring through the electrical-connection blades, and heat generated by a less-than-optimal electrical connection (loose grip, corrosion, etc.).

It can be very helpful to ensure that air from the front of the car flows over the wires and the connectors.

Additionally, manufacturers use the thinnest gauge that will do the job under optimal conditions.

If you mean to retrofit a better system, probably the best thing to do is get yourself some weather-proof relays, and run the relays with the existing wiring, using the relays to provide power to the lights through much thicker wires, with the power coming to the relays directly from the battery, with an inline fuse. This should additionally produce noticeably brighter illumination. (A little brighter, but still noticeable.)

What would cause the low beam headlight not to work when all other lights work?


If you have standard halogen bulbs:

  1. Burned out light bulb; or
  2. Fried wires between the dashboard wiring harness and the headlight bulb connectors; or
  3. Fried headlight bulb connectors.
If you have HEI emitters:
  • Failed ballast.

Have no curent to lamp plug


Burned or broken wire somewhere in the harness. Honestly, if you know the SOCKET to be good, the very best approach to repairing that problem is simply to run a 12-gauge wire from the known-good lamp socket wire to the dead socket wire. (Headlights always operate in common anyway, so there is no downside.)

Low beam headlight won't work with a new bulb


Remove the affected headlight and replace the headlight socket on the wiring harness. I've had to do this for both headlights. It's a design flaw by GM and cheap parts. The connectors are not insulated and oxidize. You have to place them with aftermarket ones. Simply pull out the wiring harness and snip the wires, use electrical wire twists to connect the new socket. Reessemble and you'll be good.

1998 Lincoln Town Car passenger side headlight low beam only.


Hi Steven, I guess you have checked the fuses? Some time (and I'n not saying this is your problem) the fuses are wired in such a way that if one blows (and the fuse is on the earth side of the circuit) there will be an output, but the circuit will either use the earth through the the other bulb or fail to earth. I would also suggest having a look at the relays and their operation. Lastly, check the earth connections again. Regards John

2004 chevy malibu headlight harness


Find out the model of the light bulb you use and go to an auto parts store. Tell them you need a plug for bulb type xyz. Then just cut and splice the wires together, matching which wire goes where from the faulty plug. Should get the part for under $10.

My vw 2002 beetle headlight bulb has been replaced and still wont work?


I believe vw uses 4 fuses 2 high beam, 2 low beam, see if high beams work,check for a blown fuse. Another possibility is a corroded wiring harness that plugs in behind the headlight. Unplug and replug the headlight socket a couple times to clean corrosion.

My headlight is not working, the driving light is very dim but the high or low beams will not work. the ground wire looks good. what could my problem be?


I don't know what model year your truck is, but is sounds like your headlamp is burned out. You can verify the wiring is working using your test light at the headlight connection. Turn on the headlights and touch the test light to each terminal of the wiring harness when the light switch is on both high and low beam. Two out of the three wires should light up.

How to replace Head light & running light switch


remove the 4 bolts that hold the headlight assembly into the chassis frame.
For example, to remove the left front headlight;
It takes a 9006 low beam bulb, OEM is 51 watts If you buy a halogen upgrade, it will be a 55 watt bulb I don't know if you can put a super xenon bulb in there, it may harm the harness, I don't know so don't rely on me for that...
Lift the hood Get a socket head wrench and some SAE (standard) sockets. Find the socket that fits the bolt head just above the headlight. I think it is a 3/8's or slightly larger.
There are 4 bolts screwed through the frame into the top of the headlamp assembly. The bolts on each end of the headlight are longer and go all the way through the assembly to align it properly.
Lay each bolt out, on the ground in the order you removed them. The middle two bolts are short, maybe 1 " and the ends are closer to 3.5" long.
Once the bolts are out, slide the headlight assembly forward. There are two bulbs, a high and low beam. The low beam bulb is to the outside of the car, or drivers side on the left, farthest to the passenger side on the right.
Most of the time the low beam will burn out since it's used 90% of the time.
The bulb has a right angle fitting with a wiring harness attached. With your hand or a channel lock pair of pliers, gradually rotate the light bulb base counter clockwise until the unit is loose in the socket holder.
Disconnect the bulb from the wiring harness and replace it with the new bulb.
Reverse the process and turn on the headlights to check you have the bulb harness properly attached before finishing up the reassembly of the 4 bolts.
Your bulb alignment with the ground should not have changed from this work. Have fun...not difficult. Takes about 10 minutes per bulb.

Installed new low beam headlight and light will


Hi, if you have a meter to check the bulb, use it to check the wiring to the socket or wiring for power when light switch is turned on. You should have around 12 volts depending on year and type of truck or auto. If the old bulb was burned, you should have power there. When you turn on switch, the other side should work and you will know you have power and it may just be corroded. Check this and you should find the problem. Please keep me posted on this, I will be around to help you. Please rate me kindly if I have been of help to you.
Sincerely,
