2016 Ford F-150 Headlights

No weird gaps once installed with clips/holes in the same places as factory. Assemblies came with most bulbs pre-installed, only need to transfer turn indicator. First side took about 45 min, second about 20. I had all tools ready, had the install video from the product page for reference, and used an adjustable-torque drill. Video instructions were mostly accurate. For the large plastic piece behind the trim: there’s a panel-clip in the wheel well, the bolt closest to the grill was 8mm, and there are two flat clips along the base that squeeze to release it upward from the fender. The part it was mounted to will sort of float around. You'll need to re-align them when putting things back together. I found aligning the two base clips first, then aligning the rest worked best. The 10mm bolt on the headlamp assembly close to the grill is much easier to remove/install with a 6in (15cm) extension. It's pretty tight to otherwise. At least for mine, no wire splicing was required, the assemblies came with the wires mentioned in the video pre-spliced. As such I did not need to use my DVM at all. However, my truck is not wired for daytime running lights stock, so I would need to do some rewiring to make that happen. As shipped, the daytime running light LED arrays were wired into the parking lights circuit. The daytime running light LEDs dim slightly (just noticeable) when the respective turn signal turns on. This could probably be alleviated by adding capacitors to the circuits or changing the wires to turn them off when turn signals come on (more in line with other modern DRL/indicator setups). I'm not sure if I can edit this later, but if I add a cap in the future (and can edit), I'll give the cap ratings used. I think the site may have mentioned some at some point too.
