Kenny,

I've tried two types of Silverstars. The fixed kind (square) I currently have on my '85 4Runner and they're head and tails above the stock halogen replacements. There really aren't too many inexpensive options when you have the fixed ones and I've had no problems with longevity (had them for 2 years, about 10,000 miles on the truck and still fine).

But, as for the H-type bulbs, I had a pair of low beams on my Subaru that burnt out after barely 3 months. Although my high beams are still going strong. I suspect it was because the low's are the daytime running lights, but still, 3 months was pretty weak.
