My plan was to get a bumper with 3” cube lights so I can reverse in the woods and fields and see when filling feeders or skinning deer. Can’t afford that right now, so these definitely fill the void of not being able to see reversing. You can see everything, works well in a non reflector housing like my square body has. You’ll see in the photos Diesel LED vs standard incandescent then field performance and viewing angle. Diesel LED customer service is also great, fixed the minor issue fast and in a hurry, thank you for being a stand up company.
