Turn Signals

Signaling Your Moves with Turn Signal Systems

The Temecula Nissan parts team has all the parts you're looking for your restoration, modification, or repair project. Turn signal assemblies communicate your directional intentions to surrounding traffic through flashing amber or red lights mounted at each corner of your vehicle. These systems include bulbs housed in protective lenses, electrical switches mounted in the steering column, and flasher modules that create the characteristic blinking pattern. Front turn signals typically emit amber light, while rear signals may share housings with brake lights and use red lenses. Vehicles like the Nissan Versa and Armada feature turn signal systems engineered to provide maximum visibility from various viewing angles while maintaining consistent flash rates.

The Operation of Turn Signal Systems

Activating the turn signal stalk sends electrical current to the flasher relay module. This component interrupts power flow at regular intervals, typically 60 to 120 times per minute, creating the pulsing effect. Current travels to bulbs in the front and rear housings on the selected side. A dashboard indicator lamp flashes simultaneously to confirm system operation. Many modern vehicles incorporate automatic cancellation mechanisms that turn off signals after completing turns. Side mirror repeaters provide additional visibility in some configurations. The system operates independently of other lighting but shares common ground connections and power sources.

Why Turn Signal Components Fail

Incandescent bulbs have finite lifespans and burn out from normal use after several thousand hours of operation. Socket corrosion creates poor connections that cause bulbs to flicker or fail to illuminate. Flasher modules develop internal faults that prevent proper current interruption. Turn signal switches wear internally from repeated activation, causing signals to stick on or fail to engage. Impact damage to housings allows water intrusion that corrodes wiring and damages bulbs. The electrical connection between turn signals and brake lights means problems in shared wiring can affect both systems simultaneously.

Identifying When Turn Signal Replacement Is Due

Hyper-flashing, where signals blink much faster than normal, indicates a burned-out bulb in the circuit. Signals that remain solid without flashing suggest flasher module failure. Turn signals that won't disengage after completing maneuvers indicate switch problems. Dim output or discolored lenses reduce visibility to dangerous levels. Cracked housings compromise weather sealing and expose internal components to moisture. Generic aftermarket turn signal assemblies frequently use substandard lens materials that yellow quickly and inferior bulb sockets that corrode rapidly. We carry factory turn signal components engineered with UV-resistant lenses, corrosion-protected sockets, and bulbs rated for extended service life that maintain proper brightness and flash rates.
