Weird electrical

[Simpler=Better]

2weeks blew my passenger lowbeam headlight, replaced it.
Last week fiddled around with the CCU, removed the unit.
Last week I also installed 2 more 21W brake lights(one for each side) in the empty housings. Currently I am not running any bulbs in the sockets.

When I tap my brakes or signal, I lose my brake lights, signals, fuel gauge, temp gauge, and tachometer for a random period of time. This happens when running or parked. The 4way blinker switch operates the 4 blinkers just fine(even if the gauges/lights are shorted while I use it) Using the 4way blinker does not "reset" the gauges/lights.

Also, the passenger lowbeam has blow again recently.

What is going on with my car? I've checked or replaced all the bulbs, none are shorted out. The rear bulb holders are not shorting out either.
