Kevin Monaghan Posted April 27, 2020 Author Share Posted April 27, 2020 Very well. I only use it for the alternating headlights and taillights while the vehicle in motion and they are killed in park. Quote Link to comment Share on other sites More sharing options...
jmurrell Posted October 14, 2020 Share Posted October 14, 2020 I am currently working on upgrading my silverado with emergency lighting. Did you have to pull your headliner out for any of the install? If so, what all had to come off? Quote Link to comment Share on other sites More sharing options...
