120 LED bulb vs normal bulb

Knowing what the LED sidelights can be like, I'd be steering well clear of eBay specials on the headlight kits, especially at this time of year. Personally I don't think you can do much better than Nightbreaker Unlimited's for halogen headlights, or 6000k HIDs for projectors.
 
Ok I just bought some Osram night brakers or something like that. (+110%). Driving back from site in London today back to kent I must say they are brilliant.

I can see a lot more clearer not too much further but well worth the money. Cost me near on £20.00.

(dipped beam only).

We have an s max with xenon lights and as a comparison its not as good as xenon but comes close. Well impressed.
 
The LED's you linked will be terrible as headlights. The ad says 5 lumens per LED which is 600 lumens. Your average H4 halogen will be about double that!
