    Howdy everyone. I have a 90 Sambar I just picked up in Seattle and brought back to Sandpoint Idaho. I have searched over this site multiple times but can’t find any info on upgrading the round headlights to LED? Do I need to replace the whole fixture or can I put in LED bulbs?

    thanks a bunch!

    If they are round headlights, you can use 7" LED headlights, but if they are a reflector type with replacable bulb, then you need an LED 'bulb' 9003/H4 most likely

    1990 would be a normal 7" round (aka PAR56 bulb).

    I personally put some Morimoto Sealed7 LED 1.0 headlights in my 1992, but I needed to make a relay harness since most Japanese vehicles use switched Grounds instead of switched hots. LumaWerx makes a "plug and play" adapter for Switched Ground vehicles, but I had relays and I am cheap so I made it myself.

    I bought a switched ground conversion kit off of ebay cheaper than I could have made one myself. I didn't go with LED's but I might since the 100w high beams really tax the hp on the engine.

    Why did you get a conversion kit if you went with halogens? Those are only needed for LEDs and some HID kits.

    Because it came with 2 relays and I could buy it cheaper than I could buy the relays and the wire I would need to install the high watt bulbs and off road lights. It doesn't take long to burn up a bright light switch when you are running 200watts worth of high beams through it.

    Oh, so it has a feed from the battery? That is different from what I am talking about. The Switched Ground conversion kits do not connect to the battery, they just have an extra ground connection and thats it.

    But yes, I agree that 18 amps through that switch is not a good idea for sure.

    Yes, direct feed through the relays to the battery.

    Yep, thats a completely different product from what I am talking about. That is just a relay harness, while I am sure it does the job of reversing the polarity, it is a more of a replacement to the headlight wiring rather than just changing the polarity of the existing system.

    Yep, those will do the job for sure, but this is what I was talking about: https://lumawerx.com/product/h4-9003-switching-ground-polarity-module

    It just goes inline and has one ground connection, so is nearly "plug-and-play". It still relies on the wiring of the vehicle to deliver the needed power instead of bypassing it. I am personally too cheap to pay $50 for a pair of these, so I just made them myself with a few relays that I had kicking around.

    Either will do the job, just two different ways of going about it.
