despite the Interweb praising various nightbreaker super duper H7 'bulbs' I found the difference barely noticeable when I tried them in my now deceased 451 Smart.
Found the same in the OHs MINI, too; made absolutely sod all difference to my eyes, the lights were just crap. Are just crap. We tried some aftermarket Chinese projector jobbies which are slightly less crap, but now the shutter for high/dip beam on one size has got lazy
As DG says, next up I'd retro-fit the OEM Xenons - which, before everyone rages about the law, there is actually a BMW/MINI retro-fit kit for.. they're 5W less (25W vs 30W IIRC), use manual levelling but add the automatic wash functionality, and must pass C&U regs given MINI sold them in the UK
Of course, that's £900 or so...
so she might just have to put up with squinting in the dark!
