Another headlight question - The 1947 - Present Chevrolet & GMC Truck Message Board Network

DREAMER1 · 03-27-2011, 01:15 AM

Ok so I may be asking the dumbest question, but whatever happened to the only dumb question is the question in asked? So please be nice to my question...

'85 type dual headlights which run vertical are "4x6" headlights, right? What are the dual headlights on '89-'91 suburban which run horizontal? I kno you an walk into the store an ask for the year, make, and model and they'll give you the bulb you need. I was just wanting to look at all of my alternatives before making any purchase...recession, the economy, etc. So help me out would ya and don't snicker too hard while you're typing in your answer.

Not sure offhand but it may say in the LMC catalogue.

I think the sub lights are definitely smaller and more rectangle'd.

Heeelllpppp somebody. Please. Yea the suburban lights are smaller, the door openings measure 4x6, but the actual bulbs are way smaller. When you look for aftermarket/ other applications besides the suburban what measurement do you use?
