[Mr JP]

Just thought this might be helpful for anyone wishing to change the standard halogen bulbs to an after market set, pictured below is my new GT, the left headlight fitted with Phillips Blue Vision Low beams (H7), High beams (H1) and sidelights (501 I think! but they are free anyway), and the right lamp has the standard factory fit.

If you look at the light given off in a vertical line directly above & below both lamps you'll notice a blue tinge from the new one and yellowish on the right!

I am please with the overall visual effect, but i have also noticed a significant improvement in light production on the road, especially when reflecting road signs etc.
