Yeah I too feel that the blue filter just filters out too much light. The eye can see daylight better than warm light but filtering the warm light leaves almost nothing left. I can see great with the second tier Sylvania bulbs without the blue tint but couldn't tell a difference with the 3rd tier silvanias with the blue tint other than spending more and having to replace them faster.Those bright white LED's on new cars just blind oncoming drivers. The blue ones are useless at night . I put some Blue bulbs in my wife's car cause that was what she wanted. I drove it at night and couldn't see so the original bulbs went back in.
I'd just replace all the bulbs at once. Probably some no name cheapo junk from amazon or ebay given how dim but still very blue white the light is i know it's those.I didn't buy any bulbs for this car, only owned for a month or so now. If it's the outer projector style one then it's either a garbage bulb or aimed way too low. I'll have to investigate when I have some spare time in the evening.
I would probably agree that the lower recessed bulb is just a parking lamp. On rock auto if I narrow down to the touring wagon, the low beam option gets grayed out.
The projectors themselves almost never fail unless the circular mounting on the housing is broken and let water in but you'd see it from within. The oem projectors on my yukon are still good as new internally. These are both very dim and very blue still which makes them look like no name junk bulbs.If it lights up but doesn't project light down the road like it should, it's either the wrong bulb or the optical system in the housing has degraded.
Projector housing is perfectly ok to use LEDs, light pattern is same as with halogen bulb and is tight. When I was replacing bulbs in my 2 cars in sig the level and pattern didn't change but light was sure brighter.Just FYI on these LEDs unless the reflector was specifically designed for it then it is unsafe for you and oncoming traffic. This is why a lot of LEDs look like garbage. If it's a replaceable bulb it's almost guaranteed that it was not equipped with LEDs to start with.
