Look up transportation code regarding LP lamps to ensure compliance.
Some cops may stop you while most won't. Doesn't make the cop a bad guy, he's doing his job. Ride legally, and responsibly, and you wont get citations or handcuffed.
Many fugitives have been caught from a simple traffic stop resulting from a simple violation such as License plate violations, Brake light, etc. Including Oklahoma City bomber, Timothy Mcveigh.
Here in Texas, Transportation code states that the LP must be illuminated well enough to be discernible/ clearly legible from within 50'. Also, the lamp must be white in color, or clear for the wise cracks.
I usually let people roll if there is any light being illuminated on the lp, if not, the stop always results in a warning for the lp lamp out, but a citation will be issued for other violations or if they bulb is a different color, such as blue, green, red, etc.
Use common sense and you will avoid most law enforcement personnel.
