Jay, you need to be sure to buy Canbus Error free bulbs with the built in resistors on those mirror puddle lights (a pair is probably $4 on Ebay, prices have come down a ton over the years). All the exterior bulbs are monitored by the Canbus, unlike the interior bulbs which can all be swapped to conventional LED's.

Alternatively, you can put a conventional LED in the mirrors but you will need to wire in a resistor on one side to trick the circuit.
