lmc is the only source for them?

I searched for a while trying to find LEDs for my 88 with the quad headlights a couple Months ago. I found a couple threads where they posted links or vendors but, they were all old.
I couldn't find any current supplier for these so I gave up. LMC was the only 1 I found that even still lists these housings. Good luck, if find any let us know!

lmc sent me a picture of those lights (first pic), the second pic is a gm headlamp from ebay. i'm confused. the gm bulbs with 3 pins look different than in 88gmctruck pics of stock headlamp.

the 1st pic the stock 88-89 mini-quad headlight bulbs.
2nd pic has the 9005/9006 plugs. you didnt show the front, so i dont know what is actually being sold. Is it a halogen or mini-quad housings w/ replaceable bulbs?

 

[eran tomer]

This is the front. It should be a genuine gm lamp. So the 3 pin bulb is not stock?

Has Anyone used the whole LED 7x6 Lights to replace the sealed beams? Link Below for example.
I have a 1988 Chevy K1500 with the quad sealed beams.

Seeing that the 7x6 is what the w/t single sealed beam setup, no it will not work with the existing quad setup. You would have to change to the W/T front end which is grille, parking lights etc...

My Bad, so they would be the 4x6 for the quad right?
Like these.

I Live in the Sticks, so I really need the extra light.
I might just go with this: https: //www.topgearautosport.com/112199/chevy-1500-pickup-1994-1998-black-grille-and-euro-headlights-set?gclid=EAIaIQobChMI4NKu6_fa6QIVjYbACh0sqgDXEAQYASABEgIPCPD_BwE

But I really like the 88-89 look.

 

[MrPink]

Even then the 4x6 is slightly bigger than the OEM ones, the ones from LMC truck fit 100% w/o modding, I did also find another company that had them too but I don't remember who they were and I didn't save the link.

Nope. I've seen people hack them into the quad housing but it looks bug eyed and terrible.

Side note, I would not buy anything from Top Gear Auto Sport. Their customer service sucks and everything they sell is over priced.
