Shade Tree Headlight Gaskets --or-- The Case of the Disappearing Irrigation Line
When you take your headlights a part, you will probably find that the gasket between the lens and the body is hard, crumbly, and generally NG. New OEM gaskets are not to be found. And the substitutes that I've seen do not appeal. What is needed is a band of waterproof, compressible material 1/8" in thickness, 1/4" wide and about 18.8" long. If this material is readily available and cheap, that is even better.
While casting around for suitable gaskets, I was thinking about screen door gasket. You know, the ribbing that holds the screen into the frame. But it is not quite large enough. On my shelf next to the box of screen door materials is a box of flexible tubing. Stuff I've picked up over time from various sources. What grabbed my eye was some green plastic drip irrigation tubing left over from a failed attempt to keep some rose bushes alive. This tubing is about 1/4" OD, about 1/8" ID, waterproof, compressible, flexible, readily available, and cheap.
With all these things going for it, it had to be a GOOD IDEA
Sure enough, a suitable length was wrapped around the reflector, the lens put in place, and the clamp band put on and tightened up. It works like a charm.
If you don't have a ready supply of drip irrigation tubing, start looking for something similar. The Big Box Stores sell clear vinyl tubing and may have something that will fit.
Remember, when all you have is a nail, everything starts to look like a hammer. I hope this helps you to start looking for hammers, or in this case, gaskets.
