My Insignia has projector headlights, and had the standard fit halogen bulbs, utterly useless, two murky piss-holes in the snow . And I didn't even get people flash me if I left the main beams on. Utterly utterly useless.
Post purchase research revealed I should have looked for 1 with Xenon lights.
roll on a couple of years and One of the P45 headlight bulbs fails, and at £45 each, I went in search of LED replacements. £40 a pair.
What a difference, wish I had done it years earlier.
Much better light spread, the whiteness of the LED is so much better than the yellow of the halogens.
And I can dazzle the idiots in their German cars that don't care that they drive on main beam permanently,
