Please remember you must keep your vehicle in full legal proper working order. Meaning, all lights operational, all license and tags current at the very least.
This is of course for your safety primarily. However, the other reason is that officers of the law need probable cause to stop you. That probable cause could be a traffic violation which includes improper equipment.
If there is probable cause for a traffic stop, then there probably will be no successful motion to suppress any evidence obtained at that traffic stop.
As always, please drive safe.
