Octane Lighting5-3/4" Halogen Semi Sealed Beam Headlight Conversion Headlamp 60/55W H4 Bulbs

I spent hours and hours scouring the web and ebay for some conversion lenses that would take H4 LED bulbs. Most are the generic projector style housings that are used on import cars. I bought a set of those and just did not like how they looked on my 64 Impala. I also did not want to pay 400-500$ for some from a retro car shop only to have to also buy new bulbs because I did not want to use HID or xenon bulbs. I searched on Amazon and finally found these. They look really close to the original style lights. The profile is slim compared to the other style projector lights which means you can run the eyelid low rider covers, or the visor covers over the lenses under the retainer rings. I chose to not put them on because I wanted to get better light output. I had not been able to drive my impala at night much because the old sealed beam lights were just not bright enough.These housings combined with a set of 80$ LED H4 bulbs which are super easy to plug and play made a literal night and day difference in light output. It lights up in front of the car like daylight. The cut off pattern and spread from these lenses is great and was just what I needed.

This is my fourth attempt on headlights for my 63 Impala. I guess the 4th time is the charm LOL. I hated driving my car at night because I could barely see. The lights were easy to install with minor improvising. The wiring adapter harness prongs for the bright lights were a little to wide to plug into the cars wiring harness. So I just bent the middle prongs on the highbeam headlights back. There are 3 metal tabs on the back of the headlights to line up the light with the buckets. They made the lights have a small gap from the light buckets. So I cut them off with a pair of wire cutters. After that it was smooth sailing. The lights are glass and look like the original ones. Also they are brighter. If you want them even brighter you can upgrade the bulbs to LED. Good price pretty easy install with a original look. I'm excited to feel comfortable driving my car at night. 😁👍🏾

The "adapter harness" seems to fit a bit too loose on the bulb and reciprocating harness connectors. The bulb fitment is dead on.But the branding on the glass didn't sit exactly centered and level. 2 of the housings had bent metal where the bulb is placed in it. Overall, pretty great quality.

I didn't want to drive at night with the poor, original sealed beams on my 59 wagon. What an amazing difference after installing these. Personally, I don't have the greatest night vision but these make me confident again. Had no fitment issues. Tabs on the back of the lenses were in the correct position. My only stumbling block was that 2 of the 4 bulbs had one terminal bent at a 90 degree angle. At first, I straightened them out thinking they were bent when packaged. Not so. These are intended to go where the original high beam lights were so I "rebent" the terminals and they are as they should be. Don't pass these up on your classic. They retain an original look but provide modern performance.

These headlights are perfect a perfect upgrade for my 1975 Oldsmobile Delta 88! Super easy to install and almost not modifying was needed. When I compared these headlights to my old factory headlights there was almost no comparison. These headlights are reasonably priced and well-built. I would definitely buy again.

I was very impressed with these, I used them on my 1958 Chevy truck with duel head lights,no damage with the shipping dilivery.

I added these to my '63 T-bird and I'm very pleased with the fit and light output.I will have to say, if you're OCD, they take some modifying. The lights you use for high beams will "clock" at about 1:00 instead of 12:00. To remedy that, I had to use a chisel to knock off the metal locator tabs and relocate them ~1/4" from where they were welded on. (I used JB Weld to reattach them to the housings.) The low beam housings worked out without having to modify them. (Remember, the original light buckets are clocked differently so you don't install the wrong sealed beam bulbs in the wrong buckets.)Another thing is you WILL MOST DEFINITELY NEED their relays, so go ahead and buy them too! Otherwise, when you run the high beams, they will blink off and on due to the circuit breaker built into the headlamp switch on your car. Believe me, just go ahead and get the relays!

As others have said, quality control is horrible... These don't fit the bezels as they should, they're clocked about 10 degrees off.If you're used to modifying Chinese garbage, they'll do in a pinch, but certainly not worth the price of admission.

Octane 5-3/4 lights are great they really are way better than the original sealed beams that came with my 72 cutlass, I didn’t need to do any mods to the headlight buckets, but did need to modify the tabs on the back of the light as they weren’t properly squared so when I put the tabs in the buckets slots they were cockeyed, so I clipped the tabs & centred the glass properly n now they work great
