1) put your hands on both sides of the brake light housing, and pull directly towards you with both hands. It’s spring loaded and will just come off the base cleanly. The one caution is that in hot sunny climates (like here in Los Angeles), the plastic can become very brittle, and tends to crumble easily. Once the unit comes off the base, you’ll see two spring loaded metal prongs with plastic clips sitting straight up. Leave them there. Take special note of the black plastic clips on the metal prongs - if one falls off, you won’t get the light to clip back in place.
2) Once you’ve got the unit out of the car, you’ll see tabs on both sides that keeps the back on the housing. Take a flat head screwdriver and gently pry those apart. Once the back is off, you’ll see the bulb socket.
3) twist the bulb then pull it out of the unit. Replace it.
the bulb type code is printed on the bulb base, any auto part store should have it.
4) snap the back cover back in place.
5) when you go to put the unit back on, on the bottom you’ll see the grooved channels that the metal prongs have contact with to make the light work. The prongs are made to bend and slide into place with pressure, so line it up, and gently slide it back onto the base until it clicks. Again, gentle is the key, I’ve had a couple of these fall apart because they were so brittle from sun exposure.
That should do it...
