I just got a real good idea. Would it be possible to combine a bulb with a amber filament and a hyperwhite filament? I was thinking about this since I have rewired turnsignals I want them to be hyperwhite when on but blink amber for the cops. Let me know if this is possible or if Im just dreaming. Maybe a project somebody could work on?

 

I don't think its they make bulbs like that. The bulb would have to be colored amber to glow amber, hence eliminating hyper whites. What you might be able to do is put a second socket in your blinker i guess, kinda like adding a side marker. but that would require you to drill into the houseing. Thats is no impossible.
