I dont think the answer applies here in Canada. Cops hold a peice of paper in front of the headlight to check the color of the bulb. Bulbs have to be dot/det approved. MTECS appear to be neather, that sucks...
what you are saying doesnt make sense - what does a piece of paper have to do with lighting up the road and being able to see where you are goin - while also letting someone else to know that you are coming their way.
DOT = UNITED STATES OF AMERICA Department of Transportation http://www.dot.gov/
If the bulbs are not DOT approved, will you get in trouble for using them?
Almost all Nokya, APC and PIAA bulbs resemble the look of "specialty" headlight systems found in some of today's newest vehicles. Although it's true they are not all DOT approved, you should not let this worry you. These non-DOT approved brands are among the most popular after-market specialty items and their use is only growing. We can honestly
(really!) say that we have never [ever] heard of any legal issue arising from the use of these bulbs, which as we say, look just like
most of the [Xenon and projector] lights you see being factory-installed on new luxury vehicles. The overall point here is why would anyone notice non-HID bulbs when the BMW next to you is lighting up the entire street w/HID?
