I got the Phillips bulb, uber bright things as they were given to me. The packaging did say that the lifespan is 50% sorter though. When i need to change i’ll probably go for a HID conversion, after going on a night ride and then jumping on the car, the halogen lights appear to be so much dimmer.
I used the HIDs for 4 years in the previous car and had no problems with the MOT, there’s a few car out there that have HIDs factory fitted as standard, but have neither washers or self leveling suspension, which muddies the water a bit.
