Bro, those lights bulbs are rip off... $2.50US for each bulb!!!!
Im gonna pull out my dash board apart very soon one day and i'll make sure that the dash will light up as i want it and use the easiest way to make it work and let you guys know how i go... Im gonna go into every store and ask what i can do and use
Keep you posted.
P.S. i dont think you should use condoms at all cos they will shrink and not shine bright anyways and maybe not LEDs cos they will only shine forward where as normal bulbs will shine like OEM...
