Headlights seem dim??

[noserider]

My headlights do not seem bright enough on low beam. On high beam they are VERY bight. The lens covers do seemed yellowed some. Do the bulbs generally need replacing for this or does it seem the lens are the problem? Coach is 12 years old.

Thanks

Edit. Just did a search and see this is a widespread problem that does not end well unless you do some upgrading from original for big $$$. Darn

I don't think headlight bulbs get "dim with age", (they either work or not)...but I would like to talk to the "genius" who invented those expensive plastic headlight lenses.
Luckily my coach came with 4 "old fashion" rectangular seal beam headlights, which, BTW, are still as clear & bright as they where 18 years, (133k miles), ago.

I just went through a very extensive headlight rebuild because my stock lights SUCK!

Generally speaking I disagree with Mel. Most sources do say that there is a degradation of halogen lights with age. However, that doesn't rule out headlight covers needing polishing. Here is one source...

One other issue is proper voltage at the headlights. I recommend you read more of what Daniel Stern writes about the whole subject of obtaining the best lighting possible.

Suspect low voltage.

Measure voltage at back of bulb for both low and high beam.

Check both to ground and across wires at bulb.

Over time head lights do get dimmer. When I started learning to drive otr my trainer had head lights that I could barely see at night with. I told him and he said that there were nothing wrong with the lights. One night he had one light go out and replaced it at a truck stop. We pulled back onto the road and at the first walmart he bought the other one. Never did admit that the went dim over time. Because we use the lights we do not notice that they are getting dimmer.
