I fitted the 80mm Halo's from eBay (the ones that flash amber with the indicators), the cost was circa ÂŁ50 which was for the Halos, controller, butyl sealing strip, stainless steel wire and a lens polishing kit. The first headlamp IIRC took about an hour to do but the second only about half the time, practice makes perfect. The time doesn't include removing and refitting the bumper, mine was already off due to the fact that I have almost rebuilt my TF with galvanised subframes, engine upgrade, big discs etc Hopefully the TF will be back on the road by July.
When I fitted the Halo's last October I researched the best bulb upgrade but never bought them. for the dipped beam Osram night breakers (H7) are the best upgrade, Osram don't make a bulb that fits straight into the main beam fitting (bulb HB3). However only this week I read on one of the MG forums that HB3a's fit, the difference being that the wiring connector is angled on a HB3a. Due to me regularly looking on four different MG forums I do not remember which one it was had a photo of them fitted, a search hasn't found it either but I did find this on "The T Bar"
"Osram Nightbreakers are probably the best improvement before hids, and are legal unlike the hids.(and before the debate starts, yes I also know people who have fitted hids and passed the MOT with them.)
The type of bulb is HB3a and H7 if I recall correctly for the TF. The HB3a is not available in the Nightbreaker but you can get HB3 bulbs. they will fit. the only difference is a 90degree tilt to the electrical plug. "
