I've had them on my bike for some time and never been hassled by a LEO. In my mindthey add to the 'old school' look of my RKC and think they look good; pink or not.
I melted my smoked lens with a bulb after I installed it. Thought it was ruined, so I drilled a hole in it and added a die from a casino. It isn't a blue dot, but with the LED bulb in there, the brake light is much brighter than it was before, and is something noone elsehas. It is good to be different.
If this helps. They are said to make the lights alluminate better, for higher visibility. They are used in any colored lens. Be it brake light, turn signals, etc..
No,.... They are not legal in Texas. You may get lucky and never get stopped for it but just be aware that you can be stopped andcited for it. It falls under, "Equipment not approved",... basically, blue is not an authorized color. Only red and amber can shin to the rear of a vehicle.
