I am really not sure where this thread belongs, so I will leave it to mod's discretion.
I am going to be replacing the tail light housing and lenses with my own design. Not the electronics though.
Are there any legal issues I should worry about? I'm in California.
California VC 26101 and VC 26104
26101. No person shall sell or offer for sale for use upon or as part of the equipment of a vehicle, nor shall any person use upon a vehicle, any device that is intended to modify the original design or performance of any lighting equipment, safety glazing material, or other device, unless the modifying device meets the provisions of Section 26104. This section does not apply to a taillamp or stop lamp in use on or prior to December 1, 1935, or to lamps installed on authorized emergency vehicles.
26104. (a) Every manufacturer who sells, offers for sale, or
manufactures for use upon a vehicle devices subject to requirements established by the department shall, before the device is offered for sale, have laboratory test data showing compliance with such requirements. Tests may be conducted by the manufacturer.
(b) The department may at any time request from the manufacturer a copy of the test data showing proof of compliance of any device with the requirements established by the department and additional evidence that due care was exercised in maintaining compliance during production. If the manufacturer fails to provide such proof of compliance within 30 days of notice from the department, the
department may prohibit the sale of the device in this state until acceptable proof of compliance is received by the department.
