Sorry to peld for stealing his question but I was going ask anyway, honest! I thought it best to start a new thread for this. I've got an SE Business estate coming at some point and was thinking about upgrading the halogen DRLs to either a brighter and whiter halogen. Possibly even led if one exists that will be bright enough and not give errors. Has anyone else upgraded or looked at options? I had a look at manuals and can't se any mention of what the bulb type even is?
