(the search button would help you out alot this topic has been mentioned many times) What ive done and has worked well : if your looking to change colors a cheap way to do it is go to wal mart and buy the lil plastic covers for the bulbs (your bulbs are 194's by the way) this will change them Blue/Green/ or Red.. second option i did after getting tired of the blue i purchased LED bulbs on ebay really cheap which gave it a really nice white color
also you can find 194 Led's on ebay very easy
hope this answers your questions
