replacement of turn signal bulb on 2007 Cadillac Escalade

unlike most vehicles the owners manual, the "Escalade" manual does not provide instructions for the replacement of the exterior turn signal bulbs, and instead advises the owner to contact their "dealer". A repair shop recently charged an owner a few hundred dollars to replace "one" front drivers sde turn signal bulb? What do you consider to be a reasonable charge for this service?

A "few" hundred dollars seems a bit high for just a bulb. However, some of the light bulbs on the newer vehicles are very difficult to get to. The front bumper on the Escalade must be moved out of the way in order to get the head light assembly out and replace the turn signal bulb. $200 - $300 may not be to far out of line.
