I just dont agree with HID,s in standard/reflective headlights as in most cases they are NOT setup properly and blind other motorists!
If you have them fitted illegally and your M.O.T garage passes you then great for you, but not necessarily for other road users
Gen 6 Projectors for example are not cheap (£350 for a set of four= £87 approx per light),but some people will pay £45 for a gen 6 coin holder that sits in the front ash tray or a optional extra JDM Flare!!!!!
So if you want HID,s put them in projectors.............end of.
