Thanks for this review.
Been waiting for someone trustworthy to give honest review and you have done that.

Have been considering going to LED on 2012 Chev 3500 because I run with lights on every trip regardless of time of day and can’t get more than 6 months out of the Sylvania’s Have tried the Silverstar, Ultrastar, Suckastar, etc. They all suck when it comes to longevity.
Anyone here have experience with the Phillips brand of halogens?

For going to the LED setup the big risk, for me at least, is to trust those fans to keep running in 105 degree heat of in –15
Just do not think the technology is there yet overall.
Must admit the beam looked better in your test than others I have seen advertised and the price is right in line.

Also the color rendering on your factory bulbs (which I noticed were Sylvania) was way better in the review, grass was not washed out looking, etc.
The locking collar is needed, they will no doubt vibrate out in time.

For now I’ll just keep stocking up on the Sylvania’s off epay as they are affordable.
It just never fails they blow just before a night run. Had one go down last Saturday, thing worked in the afternoon but right at dusk, boom no driver side light and was going on a 100 one way trip. Had to suck it up and pay auto store price to get me by.
Mad at myself for not having spare stock on hand.

Anyway, thanks again for the review!
