Upgrading to AUXITO LED Headlights in a 1977 Chevy C-10: A Review

Thanks for @Dave writing this article to share his experience with Switching 1977 Chevy C-10 headlights to AUXITO LED.
In this post, you're going to learn how to install AUXITO H4 headlights in the 1977 Chevy C-10

 Post List:

Model Information
We will focus on my 1977 C-10. A couple of notes to consider..this is a hot rod summer/good weather truck that does see some night cruises. There's a night cruise near me once a month in the summer. The other thing to consider is, that it's a hot rod with some different modifications, including my freshly installed 1 piece side windows(no wing window) and my green headlight tint. All the outside lights have switched to LEDs, so switching the headlight bulbs was the next step. I'm currently using Hella H4 headlights with Hella H4 bulbs. These are glass headlights.


Items are packed very well using an outer wrap and individually shrink-wrapped. Inside the box, the LEDs were in protective foam. Also included was an extra set of O-rings and a few small zip ties as well as an instruction manual and a thank you card.

The LEDs with a fan for each are well-constructed and durable. You see a small solder blob from manufacturing, but it's well outside the LED range and should not affect performance. In reality, this is the size of a pin head or smaller. There appear to be 2 chips per side with 3 leds/chip.

Installation Information

The First thing I did, was glance through the instructions and test each bulb for function. It includes cycling through the high/low beams and making sure the turning of the fans turning is on and off.

The H4 uses a spring type clip to hold the bulb this case the LED outer housing, then the LED is inserted into the holder. My headlight plugs are modified to allow the use of the H4 headlights. They are factory plugs with the housing cut down.

The LEDs are held in 2 O-rings. It fits perfectly. I don't see anything wrong with it. There's a line that you can use to align the LED. The instructions say you want the 2 LEDs at 3 and 6 O'clock positions.

There's a lot of wiring under the hood including extra wires to my underside LED strips. A little wire loom and zip ties help clean it up and also keeps stuff out of the fan. I wanted to make sure the headlight resistor boxes were mounted and not bouncing around. I need to do some detail cleaning and rewiring under the hood this summer...looks dirty.

I could not reuse my dust covers. The Hella bulbs mounts through the cover. If I decide yo keep this setup, I will modify the dust covers. For now, it is fine.

You are not going to see a good cutoff line in my garage. There is stuff in the way along with tons of reflective garage art(license plates, etc). But you can see the cutoff is similar to the Hella H4 bulbs.

Final Thought

Overall, a great value. Good packaging. I've always been hesitant to convert to LED bulbs these have not disappointed yet. Piece of cake to install, and after a touch of adjustment. There, you'll see things you never knew existed.The construction of the bulb and placement of the diodes mirror the construction of a traditional halogen bulb which creates a similar light pattern, rather than a blast of light. No issues with over a month of use so far.

The LEDs are way brighter than the H4 bulbs.
