purpose of roof lights?
Why do 3/4 and above pickups have a row of lights on the roof, but not the 1/2 ton?
What purpose do the lights serve, other than working-man's "bling"?

- Same reason many RV trailers, semi's, etc have them, as noted width!
Marty - I had them installed on my Prius so we could take my MIL with us. She is however within the weight limit.:B

As far as I know, any vehicle with a body width of over 80" requires them. That's why the F150 Raptor and the Hummer H2 have them. Not sure about weight requirements, but most 250/2500s and SRW 350/3500s I've seen do not have them. They are an option, at least they were when my dad bought his 2000 F250.
Width, not weight is the criterion.
Same reason wide boat trailers need the 3 center rear running lights.thomasmnile wrote:

To be a source of cab roof leaks as the truck ages. :B
LOL- I agree that few noncommercial drivers know of this law. I didn't know until I was buying my 2005 F250 and it was an option. I couldn't figure out the purpose of the lights for the driver and found out it was for the other drivers...
If the road narrows and you see those three center lights, it alerts you to hug the shoulder because oncoming traffic will be wider than normal vehicles. mich800 wrote:

The Raptor's I have seen do not have roof lights.
They are on the Raptor, but not on the roof. They front 3 ID lights are in the grill. The outer front lights are just above the bumper at the outer corners. The rear center ID lights are built in the the CHMSL. The outer two lights are just below the tail lights.
Thank you. Learn something new everyday. But this begs the question. Seems like this regulation is a huge waste of taxpayer money when the ordinary driver does not know what this means (me included).
From now on I will make sure I hug the shoulder of the road when I see three lights. :)
That does seem odd... I imagine this is something they teach you at trucker school?
When is this information used? If two truckers are headed directly at each other to cross a one-lane bridge does the truck with more clearance lights get to go first?mich800 wrote:

Me too and say we out in the public needs to learn this stuff
Don't think it is a waste, as it is there for a good reason
Like the rear axle steering that is now discontinued by GM had marker
lights on the fenders to indicate wider than 'normal'deltabravo wrote:

If that's the case you need a Bull Dog on the hood and a in-line Six oil burner......:B
Do you know the difference between a gold Bull Dog and a Chrome Bull Dog on the hood of a Mack? There is a difference. :)
The chrome Mack signifies the truck does not have all Mack components. The Gold Mack bulldog uses all Mack components. My Mack is chrome. The tranny is an 18 speed Eaton, everything else is Mack.mich800 wrote:
