Too bright mate. Far too bright. Ive saw cars with these installed, and in the dark you could perform surgery at the back of your car. They light the road up behind you. Not a good look IMO. You wanna be contacting forum member Trups, or do what I did and just shell out for the OEM units.
Yeah I remember seeing something about them being made of cheese, I'm sure mine were like new when I fitted the bulbs last time, but I'll get my dad to bring me some home from work in a few different lengths if no one can confirm it.
How much are the genuine units, and do you have part numbers please?
