Ricer lights with a blue tint are not the same as HID Xenon lamps
I am lazy so you get the first

"The German Automobile Tuners Association VDAT e.V. is warning of a new threat for traffic. More and more drivers fit out their vehicle with coloured caps for the bulbs of their headlights to visually simulate the bluish light effect of the ultra-technical Xenon headlights.
In extensive tests at the light application laboratory of VDAT e.V. member Philips Automotive Lighting, these caps, which are sold under the name ?Xenon-Effect-Caps?, were compared with the standard lights. The result was as clear as alarming: After fitting the ?Xenon-Effect-Caps?, the light efficiency was up to 50 per cent poorer what means a definite threat for traffic. Because of these properties these parts have no TÜV-homologation. A similarly miserable result was achieved with the use of bulbs with unprofessionally tinted wedge cap, which don?t have any kind of homologation, too.
The result of the test is clear: A vehicle with illegaly fitted caps or bulbs can be made out worse during the hours of darkness and the road illumination is drastically impaired. Other cars, motorcycles, cyclists, pedestrians or obstacles can be recognized later than with the standard lights. So there is a higher accident risk. Anyway the fitting of the coloured caps has a negative influence on the heat balance inside the headlights: The reflector can burn which causes expensive repairs.
Illegal modifications on the lighting equipment are no peccadillo: The type approval of the vehicle ceases to exist after fitting the ?Xenon-Effect-Caps? and in the extreme case, the insurance cover doesn?t exist anymore. In the case of a crash, the financial ruin of the car owner can be the consequence of fitting these illegal accessories. "
