It's been four to eight years since this topic was discussed here. Seems time to get some fresh ideas for fixing the nonsense that Ford committed on these vehicles.
My 2017 XLT has OEM LED low beam headlights, OEM LED Fog Lights, OEM LED DRLs, but it has OEM 9005 halogen high beams that look dim and noticeably yellow. While the high beam headlights are aimed higher than the low beam LEDs they just don't compare with the high beams of any of my previous cars (most recently a 2010 CVPI).
My first thought was replacing the OEM halogen bulbs with brighter and whiter halogens like the Sylvania Silverstar Ultra, but I remember the Ultra having a shorter lifespan and at today's prices there ought to be better alternatives (good quality LEDs are about the same price as the Sylvania Silverstar Ultras). Looking through this thread and a couple of other threads about this same problem the suggestions I have seen have included
- 9005 Sylvania Silverstar Ultras
- 9011 bulbs modified to fit the housing
- LEDs
Most of my night driving is urban where the only issue is cosmetic, but my daughter lives about 17 miles away in the middle of nowhere on the far end of 15 miles of twisty hilly 2-lane blacktop with no lights, little traffic, and occasional wildlife.
That drive needs high beam headlights worthy of the name.
One alternative I've been considering is going to more powerful LEDs such as the Sealight S7 or S2 series. The reviews of those bulbs are generally very good, although some users have expressed concern about heat. The Sealight bulbs are designed with a fan that doesn't take up and more space than the 9005 and are supposed to be a direct fit, but I notice that the Ex has the bulb housing enclosed which I suspect might result in increased heat accumulation.
I'd like to hear from people who have upgraded the high beams on a 5th generation Ex, especially anyone who is using (or has used) higher power LEDs.
