I replaced all my interior bulbs with LEDs. I'm sure they were 'warm' ones as they don't look very blue when on. I have some left over if you want them.
I also bought 6 strips of LEDs and put 1 each in the front footwells & under each front seat. I am very happy with that mod, especially since everything in my car is black on black.
The other 2 fitted neatly in the top sides of the grab rails in the back. Feel up there & you will see 2 narrow channels. The strips pushed firmly into one channel on each side & I ran the wires to the middle light so when it comes on the sides do as well. Now I can see a bit more in the back
Also, if anyone wants CREE LEDs, of any particular colour, I have heaps of different ones. I had to place a minimum order with a supplier & made up the difference with an assortment.
Oh, & I also put a single, high intensity, blue LED in the centre of the map lights - inset so not visible unless you look right up underneath it.. It comes on when the parking lights are on, but I can turn it off separately. It adds a nice ambience when night driving, although any more could be considered 'rice', lol.
Those courtesy lights look really good Paul (good onya Eugene!) What did they cost from Nissan?
