Standard 194 bulbs for dash, number plate etc. What else can I say besides the fantastic price (about 50 cents per bulb which is 1/4 the price of local auto parts). the place they are looking for. If I can get 10 I can cheaply replace all my dash headlights AND both panel light bulbs. These are not long lasting versions but they will still last for YEARS. Probably longer than the truck drove.
