Members, We will no longer allow discussion, questioning, or debate here on what color light lenses belong where, what is compliant, etc. Most members don't like seeing these discussions over and over again. It's come to the point where these threads are counterproductive, and don't add anything to this forum. Quite often, they hijack the thread and lead it off course. If you want to read up on these topics, there are numerous to choose from. Just do a search. Please note, this DOES NOT include discussion of warning devices, technical issues, etc. Thanks for your cooperation Seth G. on behalf of the EMTBravo team
