When you flip the turn signal and nothing happens, or your lights won't switch between road and field settings, it's usually this combination switch that's given up. When your turn signals stop working or lights won't switch properly, this combination switch is usually the fix. There's nothing more frustrating than being stuck with a dead signal when you're pulling a loaded wagon on the highway, and this replacement switch restores full control of your indicators and lights, keeping you safe and legal on roads and in fields. What You're Getting Single switch handles both turn signals and all your lighting functions - no hunting for multiple controls Self-canceling turn signals work just like the original so you don't have to remember to switch them off Heavy-duty internal contacts that won't arc or burn out under the load of multiple lights Weather-sealed construction keeps moisture and dirt from causing electrical problems Ergonomic lever design gives you positive feel even when wearing thick gloves Built for Real Farm Work Your Deutz 06 series tractors - from compact 4006 models to powerful 9006 units - regularly travel on public roads and work in low-light conditions. Whether you're signaling turns while pulling wagons on highways, switching between road and field lights, or illuminating work areas for early morning feeding, proper switch function is essential. These tractors serve diverse operations where lighting isn't optional - it's required for safety and legal compliance. Made to Last This switch is built to handle the constant vibration and electrical demands of farm equipment. The internal contacts are designed to carry high current loads without deteriorating, and the mechanical parts resist wear from thousands of operations. The housing keeps out the dust, moisture, and chemicals that would destroy a cheaper switch, giving you reliable operation season after season. Installation Notes Disconnect battery before installation to prevent shorts. Note wire positions before removal - taking a photo helps ensure correct reconnection. Test all functions after installation including turn signal self-canceling. Pro tip: apply dielectric grease to connections to prevent future corrosion, especially important for tractors stored outside. Check associated fuses and flasher units if problems persist after switch replacement.
