flasher lamp? are you reffering to the park light/blinker?
if so i'm after the drivers side aswell. have been after one for months now. this could get ugly.
i've found there are 2 different shaped parts, and at least 2 different styles to each shape. (long style, short style, clear/orange lens, orange/orange lens etc)
If you send me a pic of your front end i could tell you more. My supra is imported and is listed as an 87-88 so we may have the same models.
