Depends on the light fixture. Most are 120V and if an incandescent bulb will run on DC. The small solar arrays that you see on the yard lights are normally low voltage and run off rechargeable batteries (DC) that are recharged by the solar array. If you want to put a lot of money into it, you can get a large array that will output more voltage.
I discovered a couple solar garden lights have been taken over my (honeycomb) nests – that I thought were yellow jackets but it appears are wasps. (They usually build their nest in the eaves/peaks on the house.) One light had the lid loose and partly open, so I sprayed and then used a broom to knock the lid off (the nest was attached). However, the lid appears to be on tight on another and it seems that the spray doesn’t really penetrate the other sealed light fixture.
Thanks
You will need to search well and find the point of entry. The wasps typically don’t make a lot of effort to find their home. There is a hole or vent in the light the wasp is going in. If you can find it and spraying in it doesn’t work, try tying a plastic bag around it. This should suffocate them. Just have can of wasp spray available in case their friends come to visit them when you are trying to kill them.
I want to replace them with solar lights to save money. I want the end lamp post to still operate, and just remove the ones lining the driveway,
If you already have several lights along the drive, coming up through posts to a light box, there is bound to be plenty of wire to be attached, left from the post once you remove that. I’d use a plastic waterproof junction box at each post location, connecting the two wire ends together with wire nuts, wrapping them with a good electrical tape and then enclose them in the waterproof junction box before burying it. That way there’s no chance of moisture getting into the connections to corrode them.
