1996 Lexus SC 400 fog light burned ouit

Passenger side fog light is out. I assume it's just the
bulb (12v 55W H3). Have dismantled lower shroud
to get at light that I assume has to be taken out
to replace the bulb. Have taken off the back 2
washer nuts and fixture still won't budge.

Dealer says bring it in and will replace it for $35.00
What can you suggest?
