Oman Report post Posted September 1, 2009 Low-beams DRLs. That's terrible. The low-beams in the FFH are projectors. That means they are virtually useless as DRLs. They don't scatter enough light outside their primary beam to be well seen in the daytime. Factor in the fact that halogen lamps driven at a lower power cause the glass on the bulb to darken significantly and you get DRLs that will actually decrease the already lacking nighttime headlight power.

That's "eye-opening" if true! Not to say I don't believe you because I do. Poor planning on MOCOs part wouldn't you say? Quote Share this post Link to post Share on other sites
rfruth Report post Posted September 1, 2009 DRL's could be done correctly and in a cost efficient way IMO - use the parking lights (including the tail lights)((using all lights would imply the rest of the industry is doing it wrong, which they are)) also add a "DRL only" light on the dash - instead we have todays hodgepodge solution which like I said creates as many problems as it solves - this is similar to mandating bicycle helmets, don't get me wrong helmets are great, I wear one *every* time I ride but if worn incorrectly they can do some serious damage - whoever decided to use halogen lights as DRLs at FoMoCo. should be whipped with a wet noodle.

JonYou may be right, all I know is the DRLs on my VW were low beam projection and after three years they had not darkened and were plenty bright in the daytime. They operated at 80% full power. In 5 years the bulbs on my Buick did not darken. Quote Share this post Link to post Share on other sites
