Frequently Asked Questions
Is a side marker the same as a turn signal?
No, though many vehicles share a housing. The side marker is a steady amber light for side visibility.
How do I find my bulb number?
Check your owner manual. Common types are 194, 168, and 2825 or their LED equivalents.
Can water damage cause this code?
Yes, water intrusion corrodes the socket and bulb contacts, creating an open circuit.
