Size of middle bulb in passenger compartment.

[Bohica]

I know it is not 41 mm as they are too long. Why Land Rover would have a different size globe to the others beats me.
Oh remembered, it's a Land Rover thing. :D

I fitted these ones. A bright flash and then I couldn't see. When my eyes opened I still couldn't see. After a minute my vision came back. Fitted the other 2 wearing sunnies.:D

They are bright, I love 'em.

Could you use this in all 3 lights. i havent measured but they seem too big.

[Bohica]

These did fit in all three. Even the middle smaller one.

[turps]

I fitted the LED replacement for my 3 interior lights. The front one is only turned on when I specifically looking for something. As that bad boy is stupid bright.
The others are great for looking for things in the car at night.
