If the parts of the spectrum to show the color of the rocks are not there, a filter cannot add it. Filters are good for full spectrum sources but not for narrow spectrum items like LEDs. | ||||||||||||||||||||||||||||||||||||||||||||||

I didn't realize that LED sources were narrow spectrum until after I posted. Thanks. -- Regards, Robert L Bass ==============================>

Some states have some pretty serious restrictions on putting colored lights on vehicles, especially those that might lead other motorists to believe you were an emergency or police vehicle. Some prohibit any changes at all to original factory equipment. Here's one example from the first hit I found (Delaware) on Google and I know of many other states with similar rules: http://www.dmv.de.gov/services/driver_services/drivers_license/dr_lic_equipment.shtml Prohibited Equipment: Limitation in Number of Lights - Not more than four lights of 300 candlepower or more on the front of a vehicle shall be lighted at one time. Headlights must be installed no higher than 54 inches nor less than 24 inches from the center of the lamp to the ground. Red Lights Prohibited in Front - No ordinary motor vehicle can show a red light visible to the front of such vehicle. Such lights are permitted only on emergency vehicles. Flashing Lights Prohibited - Flashing lights are generally prohibited except on: Emergency vehicles, school buses, snow removal equipment Any vehicle as a means of indicating right or left turns Any vehicle as a means of indicating a traffic hazard (four-way flashers) License Plate Additions - Unauthorized frames, accessories, designs, or symbols on or attached to the license plate are prohibited. Other Lights and Original Design Change - No light, lamp or reflector that tends to change the original design or performance of the vehicle may be installed. -- Bobby G. | ||||||||||||||||||||||||||||||||||||||||||||||

Red lights can only be visible from the rear. All other colors are ok. Flashing lights are allowed only to warn of a traffic hazard, but pulsating brake lights are ok. I've seen a number of bikes with pulsating headlights and police seem to ignore them but technically, they're illegal here. > Some prohibit any changes at all to original factory equipment.
Which states prohibit any changes at all to original factory equipment? The one you cited doesn't. -- Regards, Robert L Bass ==============================>
