Bulb upgrades for 2004 K-Series SV - VVC

[Blacken]

I recently got a car and would like to upgrade all the light bulbs. I am looking to improve the (legal) brightness and efficiency and will consider spending a few quid as long as l'm getting better reliability and improved performance than the standard ones fitted.

Any suggestions would be gratefully received. It would also be helpful if you could tell me where l could source them from.

Lots on this in the archives, including this recent thread.

Are you only considering changing the bulbs for similar but better bulbs or also interested in changing to sealed beam units or the whole unit to something else?

I'm open to ideas. Will have a look at the archives.

I converted mine to Bi-Xenon - one of the best upgrades I've made and absolutely no problem at MOT time or with other road users. The increase in visibility and safety is a no-brainer in my opinion.

Ring xenon-lookalike H4 bulbs. Cheap and efficient.

I'm using these: http://www.amazon.co.uk/dp/B0166MMJOA/ref=sr_ph?ie=UTF8&qid=1455833517&sr=1&keywords=h4+led+headlight+bulbs

 

Very bright, standard h4 plugs. They do come with an led driver unit (small square box) but this tucked inside my 7" bowls no problem.
