britebox flc
 

Im looking at the britebox flc which allows highbeams low beams and foglights on all at the same time but i don;t know...in my 2003 f 350 what is a sealed beam headlight, or replaceable bulb, im guessing replaceable bulb but not positive, and in the chart it shows f-series and lists options and super duty and lists options..which one do I follor, both have different numbers....superduty? http://www.dieselsite.com/index.asp?...ROD&ProdID=358

The XL trucks have the sealed beam lights. All others have the replacement bulbs. I like the idea let us know how they work when you get it.

Now the skinny, I would not recoment using both elements on either light sets. High beam + fog is ok, Low beam + fog is ok. High beam + low beam = decreased bulb life. As both elements are in one bulb. For both styles. One just replaces bulbs, the other replaces the whole bulb/reflector. High + low beams on at the same time is for 4 head light systems IMO

Oh and thank you pclark76 for the images :-wink
