"
Reflectors on Rear
24607. Every vehicle subject to registration under this
code shall at all times be equipped with red reflectors
mounted on the rear..."
"
Reflectors on Front and Sides.
24608. (a) Motortrucks, trailers, semitrailers, and buses
80 or more inches in width manufactured on or after January
1, 1968, shall be equipped with an amber reflector on each
side at the front and a red reflector on each side at the rear.
Any vehicle may be so equipped."
So, no, it is not illegal to remove your front orange reflectors/sidemarkers in California, they are NOT required on cars.
