    1997 K1500 Rear lights bulb recommendations

    Had to replace the left rear lights circuit board, now I need to get bulbs. Not as straight forward as might seem. Question: can I use 3157 bulbs for ALL THREE positions, back up, brake, tail, or should I use 3057s? Or, should I use a mix? Another question: should I be using a double filament...
