I would not bother with LED tubes, especially, for the interior lighting. They have a limited usability in such application as under your dash to light up the foot wells. If that would be me I would go with CCFL lights. Similar to what your photocopier or scanner tubes. May have a tad of a warm-up time sometimes. Check here, there is even a forum for this stuff: http://www.oznium.com/product_info.php/cPath/21/products_id/40
I've got 2 6" neon tubes mounted under my dash and I hard wired them in instead of using the crappy cig lighter plug. What I did was run both POS wires together to my switch, grounded both NEG wires to a ground under the dash, and ran 1 POWER wire with an inline fuse to an empty slot on my fuse panel that has constant power source so I don't need the ignition to be on to run them. I've never had any problems with my set up. Good luck.
