I have used these for several years and have found them to work very well especially while running in the mountains.

At this time I run them on a 2007 Ram 3500 truck.

Much better than Sylvania Ultra's. High beam is outstanding. Ultra's don't even come close. Forget about Ford' standard halogens. But I'm really waiting for PIAA's LED's. They don't make 'em for my car yet.

<p>Nice bright white light easy to install big improvement over stock</p>

<p>The lights have much improved visibility over the stock bulbs that were in the vehicle. Whiter light and throw further down the road.</p>

I had very good headlight bulbs on my 2009 Ram 3500 but wanted just a bit more light. Your bulbs provided that for me. The lights are better in adverse conditions such as rain, snow and mist. the bulbs are whiter and brighter than the stock bulbs that I previously had in my truck. Low beam has better coverage and high beam definitely throws brighter, whiter light further down the road.
