Focus 54reg 1.6 auto. It keeps blowing headlight bulbs

Question:
I have a Focus 54reg 1.6 auto. It keeps blowing headlight bulbs - mostly the left one and usually on starting car or shortly after switching lights on. Have been using Bosch light recently - no difference. 4 bulbs in 2008!
Answer:
When the bulb heats up , the filament is prone to breaking if there is excessive vibration. You should check that the headlamp unit is securely bolted and that the bulb sits tight in its seat and the spring retaining clip is actually pressing against the bulb base to keep it in place.

98 wrangler that is in excellent shape, only problem is center brake light does not work.

Just bought a 98 wrangler that is in excellent shape, only problem is center brake light does not work. When I apply 12v to the two connectors on the rear door, the light lights up so I know that everything in the door is OK.When I check for voltage at the connector on the body, I get 8.5v. Any ideas on where to check next?
ANSWER:
It looks like it is a straight shot from the brake switch to the rear. Pin 6 (wt/tn) goes to the CAB and the 3rd stop bulb. The next step is to test that ckt at the brake switch to see if it is 12v. The wire diagram on line really stinks. I'll need to check the service manual in the a.m. to see where the harness runs in the body and if there may be any other connectors in between. I would say you've got a "green" wire in that harness it's just a question of locating it.
(The CAB is the anti-lock brake control module. The ground ckt is at the connector at the rear of the Jeep in cavity 5. )
