What vehicle Pete.
We upgraded all our lights on our Defender to LED.
For headlights I went with the Trucklite 7" which are a huge improvement of the original candles in a tin quality ones but I think there are better LED options now. The Trucklite's were the only CE marked ones available when I got them.
I went with Cibie ECE (European E-Code) H4 headlights in my Jeep. Paired with an upgraded wiring harness and Fat Boy bulbs they light up great and the E-Code have a very distinct cut-off line. They don't blind oncoming drivers even with the upgraded bulbs. Once you hit high beam look out though. I bought mine from Daniel Stern lighting here in the States but they are probably easyr to find over there. I wanted LED but at the time I couldn't find any that wouldn't blind other drivers. This was a few years ago.
