Yes, my wife had a 2008 Escalade prior to her 2015 Yukon XL SLT. She got rear ended by a 1 ton Ford. She was at a dead stop, the Ford was doing 55. Needless to say, the Escalade was completely totaled. However, these large GM SUV's are safe rigs. She was banged up and bruised, but the boys were unscathed. I digress.
One of the things we had taken for granted was the HID headlights on the Escalade. When we purchased the Yukon, the low beam output wasn't even a consideration in buying the rig. I guess I had assumed that lighting wouldn't be an issue in a vehicle made in 2015. Well, I was wrong. When the wife complains about not being able to see worth a crap when taking the boys to school in the morning, there's a problem.
The HID set-up I installed in the Yukon and listed in this post, matches exactly (in my opinion) with what we had in the escalade. We both couldn't be happier.
