    I am trying to find out if the headlights on my Coronado can be replaced with the 7" round LED lights from either JW Speaker or VisionX? My truck has plastic headlight housings with individually replaceable bulbs.

    If this upgrade can be done, please give me an idea of how to go about it. If you did this upgrade on your truck, I'd also like to hear how you liked the new lights. Thanks!

    I haven't found anything yet. I've reached out to Trucklites, JW Speaker, VisionX and Headlight Revolution. They are all eager to sell me a set of lights, but none of them can provide any details on installation in a Coronado. I have the older style round fixtures with dual bulbs.

    Not sure about you year and model, the fleet that I work on runs Coronado SD’s (FL122 SD) set forward steer axle. Originally in 2011 they went through a number of updates to the headlight assemblies. The assemblies they came out with had a polycarbonate lease ( plastic) that would crack every time they got wet. They finally settled on a glass housing in place of the plastic housing. That glass housing can be removed and a 7”round LED can be installed (a little cutting and trimming or the chrome bezel is required to make the truck lite version to fit). I’m not sure if they ran the same updates on the set back axle trucks. I notice they are angles different.
    I suppose, if money isn’t an option, you could buy the new SD housings ($275 per assembly) tear them apart just for the bulb cage, cut the bulbs from your original housing ( not break the 3 ball studs mounts from the back of the main housing) and pop the cages into your assembly. I’ve done that in a bind because I had the original housing rat holed, the updated version was broke, and I didn’t have a new one on the shelf.
    As for operation, it’s a huge difference, the truck light versions was an all around improvement. We bought a bunch and got the price to @215 a peice. The later models have an after market “??Maxima??” ThAt are only slightly better than the OEM glass versions. If your spending the money and have any chance in running in ice or snow, get the heated version, ice build up is the only complaint. But that’s my book, hope it helps

    If your replacement assemblies have the glass lenses in them it’s really simple. Undo the headlight and turn/ clearance harness’, a 13mm or 1/2” will take the assemblies out of the hood. A Phillips screw-drive removes the chrome bezel and the glass bulb lense/bulb. Install the LED bulb lay the bezel back on, make 3 marks where the alignment tips of the led bulb touch the bezel, use a die grinder, cut off wheel, or other high-speed cutter and notch out about a 1/8” around your marks. Screw on your bezel and install the assemblies back into your hood. Make sure you aim them the new LED’s can blind people.

    Sorry I am so late responding. Thanks for your input.

    My Coronado an '06 and is equipped with the plastic assemblies and plastic or polycarbonate lenses. It is a Grote assembly (7" round headlights). It does not look like I could cut away enough of the existing housing to install the JW speaker housings in their place.

    I've purchased a new set of Grote assemblies and a set of JW Speaker adapter assemblies to see if i can cobble something together. Unfortunately, I haven't made much progress yet.

    IMG_2364.JPG Finally!

    Took it to the freightliner dealer this morning to verify the alignment. Don't wanna be that guy!

    Both looks great. I have a 2007 and want to do what you have done. What did you end up having to modify? Also what are those running lamps?
    Thanks

    I ended up purchasing all new stock lighting assemblies (made by Grote.) The two complete headlight assemblies, I just stored on the truck in case there was ever any problem with the conversion. The running lights are new factory fixtures with JDM Astar Led bulbs in them. I also purchased the JW speaker headlight mounting kit, but ultimately only utilized the fixture retention rings.

    I then removed the factory fixtures and went to work on them. I removed the bulbs and the bulb mounts (save the self threading screws). I very carefully cut away the lense only, being sure to leave the base housing as undamaged as possible. I cut away the back of the fixture, only removing the backing, but none of the corners that give it strength, and staying well away from the attachment points.

    The new light, just like the old fashioned sealed beams, has "indexing" bumps or tabs on it to ensure that it is secure and aligned properly in the fixture. The old housing must be notched to accept these tabs securely and keep the light tight and oriented properly.

    Once the new light was properly fitted into the housing, I used the fixture retention rings from the JW speaker kit to hold the light in place and used the self threading screws (although I predrilled the holes) retained from the bulb mounts to fasten them. You can see the trim ring in the background of the second photo. The trim rings will need modification as well. The mounting flanges are bent flat, and new mounting holes are made to allow the screws to fasten to the thickest part of the original housing.

    Unfortunately, I only have a few photos.


    Note: I used a Dremel tool to cut the fixture.
    Be sure to apply uniform pressure when marking the holes and installing the trim/bulb retention ring. The fixture must not move at all. You know how these rigs vibrate!
    When reassembling, be sure to apply blue loctite to the screws holding the headlight bezel, and be sure not to over tighten them.
    I made sure that I could return to stock lights and wiring, while on the road, so I did not make any changes to the truck or the wiring.
    I combined two aftermarket wiring harnesses into one in order to make the lights work properly and avoid any changes to the factory wiring.
