I bought some white looking ones for a previous Astra J, looked whiter, but weren't actually any brighter. Led's are good, but unless fitted from factory are not legal. As it's hard to judge from a photo.
I get where you're coming from by that Chris but it's fairly obvious to anyone who knows even a little about cars (and you would've hoped the mech's doing the MOT would know ) the difference between a Halogen incandescent headlight output and an LED headlight output. I don't know if I'd be willing to risk that in an attempt to get it through the MOT.but remenber the mot tester can only visualy look he cant not remove the dust cover to see what bulb you got in,so if there are no wires coming out and the aligment is within spec it should pass
