Review on PHILIPS X-treme Vision +130% Headlight Bulbs (Pack of 2) - Enhanced Visibility (H4 60/55W) by Rick Kreutzer

I gave 3 stars because I'm not sure if the problem is entirely related to a bulb failure. It was a combination of the description, the age of the car, the electrical system and the lightbulb. I wanted a brighter light so I bought these for the combination of brightness and price when my driver's side headlight burned out. I made sure they fit my car which is a 1993 Honda Del Sol. They came and went the moment I turned on the light on a moving car. (They worked fine when the car wasn't running. It was weird). It also caused some other electrical problems until I replaced brand new but now blown lightbulbs with the cheapest I could get my hands on. I don't know the exact problem, I just wanted other people to be a little cautious with older cars.
