can you take strobe lights in car wash

[DeMolly]

No, you should not take a car with strobe lights through an automatic car wash. The mechanical brushes, high-pressure sprays, and harsh chemicals pose a significant risk of damaging or dislodging the lights. Strobe lights, especially those not installed as original factory equipment (OEM), are not designed to withstand the intense physical forces and cleaning agents used in tunnel-style washes.

The primary danger comes from the mechanical brushes and cloth strips. These components can snag on the external housing or wiring of the lights, potentially cracking the lens, breaking the mounting brackets, or pulling the lights completely off the vehicle. Even in a "touchless" car wash, the high-pressure jets are powerful enough to force water past seals, leading to internal condensation and electrical shorts. Furthermore, the alkaline soaps and waxes can degrade the plastic lenses over time, causing them to become cloudy and yellowed, which severely diminishes their brightness and effectiveness.

The safest method is always a gentle hand wash. If you must use an automatic wash, your only potentially safe option is a touchless wash that uses only high-pressure water and soft-touch chemicals. However, this still carries a risk of water intrusion. The best practice is to remove easily detachable strobe lights before entering any automatic car wash.

Potential Damage Type	Cause in Car Wash	Result
Physical Damage/Dislodging	Contact with mechanical brushes or cloth strips	Cracked lenses, broken mounts, severed wiring
Water Intrusion & Electrical Failure	High-pressure jets forcing water past seals	Short circuits, bulb failure, corrosion
Chemical Hazing	Harsh alkaline soaps and detergents	Cloudy, yellowed lenses reducing light output
Adhesive Failure	Heat from dryers and chemical exposure	Lights becoming loose or falling off

Take them off. Seriously, it's not worth the risk. I learned the hard way when a brush snagged the wire on my light bar and ripped the whole thing off the roof. The car wash company wasn't responsible because of the "aftermarket equipment" disclaimer. A quick hand wash with some soap and water is all you need to keep them clean and functioning perfectly. It takes five extra minutes and saves you a huge headache and repair bill.

From my perspective, it's about preserving the equipment's purpose. Strobe lights need to be reliable and bright. The chemicals in an automatic wash can haze the plastic lenses, dimming the light output when you need it most. The violent shaking and high-pressure water can also loosen internal connections. For something that might be used in an emergency situation, you can't compromise its integrity for the sake of a quick wash. Hand-washing is the only way to ensure operational readiness.

Think of it like this: you wouldn't put a regular flashlight through a dishwasher. Car wash machinery is brutal. Those spinning brushes have immense torque, and they don't know or care that your strobe light is fragile. The mounting brackets for aftermarket lights are often just clamped or taped on; they're not built to withstand that kind of abuse. It's a simple equation—the convenience of a five-minute automated wash versus the high probability of expensive damage. The choice is clear.

The absolute safest answer is no. However, if you are in a situation where you have no other option, a "touchless" car wash is your least-bad choice. It eliminates the risk of physical impact from brushes. But you must understand the trade-off: you still risk water intrusion from the high-pressure jets. Immediately after the wash, thoroughly dry around the lights and inspect them for any moisture inside the housing. The correct procedure, always, is to hand wash around the lights carefully, avoiding direct high-pressure streams on the seals.
