This is a very easy and cheap mod, all you need is a Phillips screw driver and some LEDs bulbs. The bulb size you need for changing out the licence plate light is 168/194. I got 2 bulbs with 6 SMDs each for $5.50 shipped from eBay.
- There are 2 screws that hold the plastic housing to the wiring harness. Between each housing and the harness there is a piece of weather strip.
- To save some hassle when screwing the housing back to the car, only fully remove 1 of the 2 screws on each housing, leave the other screw attached (and holding) the housing to the harness and rotate the housing a 180 deg so you can swap the light bulb out.
- LEDs bulbs have + and - terminals too. Make sure you turn on the lights to check whether or not you put the bulbs in correctly before screwing the housings back on to the car.
