Subject: Radar Detectors v. Chevrolet Trailblazer

Hi All,

Some interesting news... I recently emailed Mike Valentine regarding a problem I was having with my V1. Some of you may want to try this!!!

PS This is not another rise of a Radar Detector Fight, but I believe it should effect all RDs!

Mike's Response:

Hi Robert,

I have heard of this just recently. The Trailblazer probably has a neon-powered Center High Mounted Stop Lamp (CHMSL). For sure, the BMW E46 (newest body style 3-series) cabriolet has one of these neon CHMSL's on the upper rear of the trunk lid. If I follow them in traffic, the V1 always goes off for laser when they step on the brakes, sometimes from impressive distances ;(

I don't think there is an easy fix since the neon infrared energy has a really fast rise time, just like a laser pulse. The pulse repetition rate is within the expected range for real laser guns, making a real monster of a software project: Try to get rid of the neon without getting rid of laser guns, even occasionally. Not simple or reassuring.

Also a problem with the Oracle sign in Redwood Shores, most Pizza shop OPEN signs, and a wide variety of red neon.
