I put on some cheap fog lights from Walmart under my front bumper. These are turned on via a relay hooked to my headlight dim power line. These cheesy little 55 watt fog lights turned out to be dramatically brighter than my headlights. So, I started looking at my headlights. I saw a little reflective cup covering the bulb. I wondered if the reflective surface of the interior of this cup was still good. I removed the bulb and looked into the cup. It was totally black and powdery looking inside. This headlight assy is glued together and I could not open it. So, I put in a screwdriver and bent this cup as far down into the lower headlight assy as possible. I then cleaned the black paint from the front of the headlight bulb and reinstalled it into the plastic headlight assy. The difference in lighting between the headlight that I had not modified and my newly changed headlight was huge. I had considered replacing the 55/60 watt bulb with a 80/100 watt replacement. I did not do this for fear of melting the plastic headlight assy and I would also have to install yet more relays to power these new amp hogs. I offer this as a cheap way to improve the lighting on these old cars. BTW if anyone has successfully used 80/100 bulbs, please comment.
