:D I also just got a LCD repir Kit from Mikado and let me tell you it is great to finally see my temp/clock display. I replaced LCD myself, fairly easy to do with right equipment. Like migirdech said, it comes with replacement bulbs and the LCD is an exact match to the original. I would recommend getting one from Mikado. Another advantage is that if you get it from Mikado, you can get one for either the 90-92 LS or 93-94 LS. I know this because after winning the auction on Ebay, Sammy from Mikado called me to ask if I needed the LCD for a 90-92 or 93-94 model LS.

The backlighting on mine stays on even when headlight are not on. It has always been like this even when my LCD was blacked out. It turns on as soon as you insert key on turn to ACC. Don't know if it changed for other years.
