First Laser Jammer manufacturer to offer a true "hidden" Laser Jammer (that jams effectively) will be #1.
Cutting grilles and exposing "heads" is a "no, no" in areas where RD's are illegal. Also US states where anti-LaserJammer laws are extant or contemplated.
The 2-section design (head/s and CPU-Interface) is not the "ultimate" format.
We need a 3-section design:-
(1.) Tiny head/s (waterproof) with 1 x receiver infrared LED and 1 x jammer~laser-diode. Would have minimal amplifier circuitry inside waterproof housing. Size - no more than 1/2 inch square (or round equivalent).
(2.) Small CPU Box (waterproof) for processing (fits inside engine bay) with 2 - 3 feet cable connection to heads. Long cable connection to interior.
(3.) Junction box (with rest of the brains) inside the car. Switches etc connect to this "interface".
Surely this aint (sic) rocket science?
