Brake Light problems of the 2006 Lincoln Town Car

On the previous day I had replaced the left side low beam headlight bulb twice which did not fix the problem. Thought it would be a simple fix for a burnt out bulb. Turns out the origional bulb was not bad at all. Took car to dealer for diagnostic check. Problem turned out to be a lighting module ($659. 25 part) not repairable, that had to be programed ($239. 63 fee) by dealer before being reinstalled. This module also affected my brake lights which I was told were not working. If I had been out on the road when this occured instead of my local traffic area I think it could have been a safety issue. I feel this would have been a safety situation since I never knew my brake lights were not working and also not being able to get my headlight to work. What if both headlights had gone out while I was driving at highway speed because of this module. This situation also put me as car owner into the position of not being able to fix a simple headlight problem and turning it into a major car repair ($905. 61 bill). I feel the use of modules to control headlight lighting is a major safety issue. It should not cost nine-hundred dollars to fix a headlight problem. I foresee down the road a whole lot vehicles with these modules having no lights. So much for the modern era. Give me the old style electrical system with just wire and fuzes.
