I'll vouch for the Lereyn and
pulser. With tinted rear window, you can't see the light strip until the LED's fire. The Lereyn LED strip needs to be heated with a heat gun to adjust the angle so its horizontal when installed in the top beading of the rear window. The pulser is a great attention getter, especially with a fast illuminating LED strip. If you can stop on a dime, both are a great insurance policy.
