Review on LASFIT Headlight 7600LM Bulbs Adjustable by Jerry Frey

Anyone complaining about poor penetration doesn't understand how lighting works. They are very bright, especially up close. This affects how your eyes adjust to seeing objects in the distance. It's not that they don't penetrate, but your eyes get used to such bright light up close. They fit easily into my headlight housing with slight adjustments to the H1 bulb terminals. The base is round, which makes it difficult to bend the clip to attach it. ****DO NOT INSTALL them in the reflector body! They are designed for projection purposes. They will constantly dazzle others and be dissatisfied with their performance in reflector headlights.
