These fit perfectly in place of regular H4. Light pattern is very close to same but you can tell the difference. It is super bright compared to halogen.When you twist it into place it mounts firmly. In all, I'll recommend these. These look and feel very good quality bulbs. Good installation instructions came with the bulbs and a installation video is also available.

excellent build quality good bright white light could be a little hard to fit in light units with tight space in engine bay but much better than some of the cheap led lights available

After buying various halogen "upgrade" bulbs over the years I stumped up the 80 odd quid for these and oh my gosh wow what a difference!! These are absolutely amazing and I can't believe the difference from halogen, it makes driving in the dark and rainy so much easier and actually lights up the whole road. I did slightly adjust my headlamps alignment to suit to get full advantage, but I guess this won't be necessary for most people as I think mine were a bit out anyway. P.S not 100% sure but they may not be legal for road use in UK however they should be mandatory if you ask me.

Easily installed, 100% compatible with H4 type of bulb mounting. Noticeably brighter than conventional H4 halogen.
