I know halfords can sometimes be a bit of a cuss word but last week I found I had one head light out on one side and one side light out on the other so decided to replace all four, I actually found that halfords LED 5w5 wedge bulbs were really good once fitted as I was sceptical. As side light bulbs they are great extremely bright and give the front end nice look. As for dipped beams I used a halfords XID Xennon look bulb that is extremely bright and has that night bright white look and feel to them. Needless to say I was sceptical but very impressed now! Lets see how long they last but honestly its a much cheaper alternative if you don't want too shell out for a flu HID conversion etc. I also have Halfords ultra bright main beams and they also give a nice white light to them.
I must say I do not work for Halfords or any counterpart there of.
Custom air nobs are amazingly easy to fit and make a massive difference to the car for very little money. (about £20 I think they were) look through the forum and there is a guide somewhere for how to replace them. Pick them up from ebay. The chinese company i bought them from also sent me a weird lump of tea :s
Also LED lights in the vanity lights make a nice difference.
