Funnily enough, Iâm in the process of swapping my headlight bulbs now. Some chap on FB recommended a set of LED bulbs and I bit the bullet as they were pretty reasonably priced. I had switched the incandescent bulbs last year to the best bulbs I could find and was still disappointed by them. Itâs all down to the projector style lamps ultimately. Anyway, Iâm giving these a go and time will tell if theyâre any good or not or will lead to investing in even better quality items.
To all the âexpertsâ who will no doubt jump all over the legality/mot problems etc etc of this change, please note, I donât care.

We know you donât care! 
But others might perhapsâŚ
Of course what one does before and after an MOT is perhaps a different matterâŚ
I must confess I did âTryâ some LED bulbs (The best I could find) and they were actually worse than my current H7âs and was very disappointed so they went back.
They were very white (like yours in the garage) but the actual brightness on the road was appalling.
All the best as always. 
For the legality aspect for others.
Section 4.1.4 of the current MOT inspection manuals for both motorcycles and cars and passenger vehicles states âExisting halogen headlamp units should not be converted to be used with high intensity discharge (HID) or light emitting diode (LED) bulbs. If such a conversion has been done, you must fail the headlamp.â
