Gibby, you connect 2 hoops connectors to the battery. 2 new H4 plugs plug onto your blubs and 2 spade connectors push into your old loom on the battery side. I would use male H4 plugs, but I haven't found anywhere in the UK that sells them
Took me about 10 mins in the dark to fit one to a mates car. He was using 60/55w phillips bulbs and I'm sure his is brighter than mine.
If you use 100w bulbs without this loom it will melt the original loom which will be a pain to replace as it's all routed through the car!
There's no law about how bright your lights can be as long as the bulbs are E marked. All the new cars with Xenons are brighter than ours!
For the MOT they only check the alignment not the brightness so you won't blind others unless your lights aren't aimed right or you just want to anyway if they're using their fogs in the day!
