I had been having trouble with CMS indicating the headlight was out. I decided to change the bulb. I found the connector almost completely melted and the reflector loose inside the light. Any thoughts on a fix for the reflector?

The connector can melt from installing a higher wattage headlight bulb, or a slightly corroded bulb or connector contact. There is a ceramic connector available that will not melt. If it was a higher wattage bulb it could have also melted the adhesives that hold the reflector together.

I was using a Sylvania silverstar. I did replace the connector.

I'd think the silverstar bulb was not hi watts. why did you replace the connector? If both the connector melted and reflector loose maybe something was intermittent causing surges in voltage/current or just a high resistance that heated up?? what happened? I'm waiting for a 75W Osram rallye H4 bulb to install in my '84 VR and I didn't buy the ceramic connector.

I don't think the 2 problems are related. It's still usable with the loose reflector.

This is what I mean.

Since it is the low beam and ground connectors that are melted, it is possible that that a filament broke in the bulb and landed in such a way as to short the bulb internally to draw more power but not quite enough to blow the fuse. Since it is both terminals that melted it is less likely that it was due to a bad or corroded contact. The odds of 2 out of 3 having the same corrosion at the same time it much less. This is all just a WAG on my part without being there to check things out.

 

I would get a new connector and a new bulb to try out.
