What happens when a turn signal bulb fails?
Step 2 – Inspect both the front and rear of the vehicle to identify the directional signal bulb failure. A turn signal system is designed to operated on a specific resistance, when a bulb fails this resistance changes causing the system to operate at a faster pace.
Where are the bulbs on a turn signal?
Tracking down a loose wire or a ground that isn’t grounding can be a pain in the neck. But let’s get to it. In order to replace your bulbs, you had to access the back of the turn signal housings.

What happens when you break the turn signal bulb?
This unit makes then breaks the electrical circuit that turns on the turn signal bulbs. The cycle will continue as long as the directional switch is turned on. This unit relies on heat build up caused by electrical current flow to determine when to break the circuit.
