Courtesy lamps
These are the little lights in the doors that light up the ground when the door is open, and help other cars see your door at night. The Valenti product is nicer/better than just a replacement LED bulb; it is a specificially-designed flat panel that fits in the stock lamp housing.
You just pry the lamp unit out, take it apart and insert the new panel, then plug the bulb base for the panel into the stock bulb socket.
Assembled
It's really bright!
Vanity lights
These are the bulbs in the sun visors. The stock ones are pretty weak and yellow. The Valenti units are sort of a hybrid bulb/circuit board.
Again, you just pry off the lens, pull out the old bulb. (Hot if it's been on for a while!) Then just press the new bulb assembly into the socket. Put the lens back on and you're done.
Side markers
Some of the aftermarket units function as a turn signal and require extra wiring. Some of them are molded badly and they tend to fall out. The Valenti is just a replacement lamp -- no additonal functions over stock -- but it's made very well and the fit is excellent.
The come in clear, amber, and smoke. Install is very easy. Take out the factory lamp housing, quarter turn to free it from the bulb socket, put the plug for the new lamp in the socket, and put it back together.
Smoke
Clear
Amber. (Sorry for not having my own photo of these.)
Clear on our white BRZ
They light up nice and bright, even the smoke ones.
I think that about covers it. The only thing I didn't go into is the Valenti center rear fog/backup light unit, but I'll get to that another time. Yes, we do stock and sell these items, on our web site, which is in my sig.
