I use bulbs like the following ones in my dashboard. I fitted them in 2012 and had no problems or failures in them since. They are much brighter than standard and the dash looks much better with them fitted. They also use less power and generate less heat than normal bulbs. I chose these because LED's are usually quite directional and do not provide a good spread of light so with these there are 20 LEDs per bulb emitting light in all directions.
