Review on SYLVANIA 9004 SilverStar Ultra - High Performance Halogen Headlight Bulb - Brightest Downroad, Whiter Light (2 Bulbs) by Steve Douglas

One of the two I bought lasted about 9 months on my 1997 Infiniti I30. I still gave it 4 stars because it really helped me see better as I regularly ride unlit trails through the forest in total darkness. I'll admit I haven't compared them to standard brand new bulbs, so I'm not sure how much better they are. Nevertheless, I bought them again because I like the whiter color and I can see the road better. Considering the lifespan and price of around $36 per pair, that's a small price to pay for better visibility. PS: YMMV - Different people estimate the lifespan of these lamps differently. I would recommend making this purchase with the expectation that they won't last a year/years. I recommend reading more reviews before making a decision.
