I read about the "challenges" people have had with the daytime running lights so I ordered a set of LED bulbs as soon as I got my JGC Loredo. When I'd had it for about three weeks I got the Auto Electrician that my dealship uses to instal them (they were doing my towbar wiring at the time). They found that the plug for the left daytime running light was "heat discoloured".
I went straight from there back to the dealership who initially tried to blame the LED bulbs! A quick discussion outlining the discovery process fixed that! During this exchange they tried to tell me the headlight assembly is worth in the vicinity of $4500, no, that is not a typo. That figure is laughable by the way, a little effort on google finds them for around $700, with HID. They are fitting a new left hand headlight assembly this Friday. Commendably this was their solution, the assembly comes with a new daytime running light plug.
So, long story short, check your daytime running light plugs as you switch to LED bulbs. Search for 3157+LED, lots of choices. I am happy with the ones I have installed, brighter than the original bulbs, lower power draw (and less heat), longer life and they look great!
I do like the look of this style of bulb and would look at them as an upgrade/replacement 7 5 Watt High Power Xenon White Reverse Lights 3156 3157 LED Bulbs Backup H3 | eBay
Hope this helps.
