Visually inspect the switch bulb for obvious damage, wear marks or fluid leaks

Frequently Asked Questions
How do I check if switch bulb parts fit my car?
Use your vehicle details (make, model, engine) to confirm fitment before ordering switch bulb parts. Matching the exact engine variant helps you choose the correct part first time.
OEM vs aftermarket switch bulb: what's the difference?
OEM parts match the original equipment specification. Aftermarket parts from quality brands are compatible alternatives that often meet or exceed OE standards at a lower price.
How can I find the OE number for switch bulb?
Check the part on your vehicle, your service history, or manufacturer documentation for OE/OEM reference numbers. Cross-referencing OE numbers is the fastest way to find compatible parts.
