Was reading a car mag in the dentists and noticed that Phillips X-treme power bulbs came best in their comparitive test 'by miles'(to quote)- although the single filament ones H7 were being tested not the H4 which we need. I have had good results with their H4's and recommend them for use in the 'proper' rectangular lights. The difference compared with ordinary bulbs is spectacular. See www.powerbulbs.com for a reliable on-line source .( 25% off sale on at present.)

I have a set of £23 Halfords Bright White lamps in the dipped lights on my V8 S type. 55Watt and road legal. Much improved lighting compared with the OE spec lamps. Recommended. Even in daylight, they look much brighter.

If you can`t get to Halfords, there are loads available on e-bay under Jaguar parts and accessories.
