Peterbilt 389 headlight cluster..

Those are just 357(?) single squares can try and find a used set they are expensive new

 

Yeah those are spendy because they weren’t real popular at the time. Try salvage yards and maybe even body shops. Call Peterbilt dealers and see if they have any takeoffs laying around. As long as they’re not dented they can be polished and brought back to life.

 

From what I understand you will have to change some wiring to get the old lights to work, I’m assuming just some plugs/harnesses. I’ve never been around when someone is swapping them out.

 

It was actually a very easy switch out on my 2015 389 Glider. The lights I have on now only have 3 wires as I have no turn or running light on them. The lights I had before had turn and running lights so it was a couple more connections. I kept my plugs from the OEM lights and made the sealed water proof connections.

 

@Banker how was the light switching from the factory ones to the other ones? I want to switch to the dual square 359 lights but not sure how they’ll light up the road compared to the factory 389 lights.

 

The round single ones I had first were ok, but personally I like the dual lights better. There really shouldn’t be a difference for me as I rarely use my high beams, but for some reason my current lights do better. I would like to put the brighter new style bulbs in them, but I don’t want to be that guy that blinds everyone on the road like most vehicles do nowadays.

 

I put these bulbs in and it made a world of difference on the single lights. The bulbs that came in my current lights work great. I am not sure what bulb it is as I haven’t changed one yet.

 

I feel like they are as good as the factory lights were. The JJ bracket bolts right up using the same holes as the factory lights did. I can’t think what they are called, but it is basically the threaded part of a bolt that screws in to the JJ and then goes thru the hood and you put a nut on the other side. They don’t ship these with the JJ brackets and you will have to get these yourself. You can make them yourself, but I went to the hardware store and they cut them to the length I needed.

 

As ugly as those alien eye lights are they do throw pretty good light, especially compared to the old standard sealed beams
