Bet your bootie it's still enforced. National City CA. Oct 2018. Highway Patrol and looked like new Ford shiny black pickup, lights flashing Union 76 gas station on off ramp of I-805.
Female cop, busy writing. Driver with his hand resting on bumper mounted light bar. Time, around noon. She was standing close to the light bar. Couldn't have been a coincidence.
Ranging transmission through gears, light bar flashes as it passes R reverse.
When I had a bumper light bar I got glared ac by San Diego cops. An Arizona highway patrolman walked over at a Love's Travel Stop and saw I had disconnected the plug to the bar. That was in 2010. He waved his hand and turned around.
I don't like tickets.
