Review on 🔦 Kohree LED RV Porch Light 12V Exterior Utility Fixture, 320 Lumens, Replacement Lighting for RVs, Trailers, Campers, 5th Wheels. White Base, Clear & Amber Lenses, 2-Pack by Draven Invert

Hail cracked the lenses of our original incandescent bulbs, so I decided to replace them with these, one on and the other off. They are very bright, appear well made, but do not work in the installed position. When connected directly to the battery, the old light and the two new ones work perfectly. When connected to the wires at the attachment point, only the old light bulb remains lit. (See photos.) My digital voltmeter shows 13.87 volts DC across the battery and leads. I contacted the seller; They had no explanation but graciously sent two replacement units in the hope that this would fix the problem. It's not like this. If they worked as intended they would be worth five stars all day, but the bottom line is they're not. Any electrical engineers suggest a solution? If I get any suggestions and one of them works, I'll update this review.
