I got spammed these on FB, and they look pretty good.

It got me thinking can I get a brighter LED headlight bulb too? For a 2012 Diversion.
Yep, loads available
I changed the (Notoriously weak) bulbs in my Caterham to LED H4`s and the difference is quite literally like night and day
Yes and no.
Yes you can get cheap led h4, h7 etc bulbs.
They are abysmal.
The problem is that a filament is a very small point emitting the light, so the reflector and lens produce a beam with a nice sharp cutoff. An LED is much bigger and the result is half of your dipped beam now ends up pointing at oncoming traffic. Therefore they're not legal.
There is a Phillips led bulb that is approved, but its a lot of money. Might be worth it on a new car you expect to keep for a long time if the alternative is buying nighbreakers.
There's some beam shots here of what happens if you juat use led bulbs off amazon/ebay/wish/aliexpress :

Potential MOT failure.
MOT tester looks for LED lamps, and if were not fitted as OE, then....Fail
No, I cannot see your indicators.
Not bright enough.

Might as well join the party, it seems like every other car on the road has retina spitting abilities on dipped beam.
