I got my bulbs from advance auto parts.The part number is right on the bulb itself,atleast mine were in clear raised letter.2 bulbs for the map lights,and one for the dome.
Go to VLED's/Superbrightled's to get them. And PAY for them. Dont cheap out. If you do they will last 2 months and you will be replacing them. It become a hassel. Trust me and just spend the money on the good bright ones. Otherwise you wont be happy. I recommend getting the 5000k color. Gives it a nice whiteish/sorta blue light.
Mine are fine.I have had mine for about a year now,no problem at all.Even my mirror marker lights are fine and i got those Thru Advance Auto.N those have seen mud,truck washes,power washing,rocks,and still fine. I do see your point on not cheeping out.However not everything you buy law priced it cheap,lol.
I went to the parts store and picked up leds to change out my interior lights. The result was not very impressive. I then took the advice and ordered from vleds. I replaced these today and the wow factor floored me. I highly recommend the vleds. They are not cheap but well worth it imo.
