Front Turn Signal Assembly 8-97365172-0 (RH) & 8-97365173-0 (LH) For ISUZU 600P NPR NKR 4KH1 — 12V Corner Lamp Set, Weather-Resistant Lens, Direct Fit

The Front Turn Signal Assembly covering OEM references 8-97365172-0 (Right / RH) and 8-97365173-0 (Left / LH) is a verified replacement lighting set for ISUZU 600P, NPR, NKR, NQR, and related N-Series commercial trucks equipped with the 4KH1 diesel engine. These are the front corner / turn signal lamp assemblies mounted adjacent to the headlamp, serving as the primary directional indicator and parking / side marker on each front corner of the vehicle.

The two part numbers form a complete left/right set: 8-97365172-0 (8973651720) is the Right-Hand (RH / Passenger Side) assembly, and 8-97365173-0 (8973651730) is the Left-Hand (LH / Driver Side) assembly. Each unit is a complete lamp assembly designed for 12V electrical systems, with a weather-resistant, UV-stabilized lens engineered to resist yellowing, hardening, and cracking under high heat and sand exposure. The internal sealing structure is designed to isolate sand and dust, slowing corrosion of the metal socket and maintaining normal lamp function in harsh operating environments.

1. Left/Right Pairing: 8-97365172-0 is the Right (RH) unit. 8-97365173-0 is the Left (LH) unit. They are mirror-image designs with different housing angles and lens patterns. They are not interchangeable side-to-side.
2. 12V Electrical System: Both assemblies are confirmed for 12V operation. Confirm the vehicle's electrical system voltage before ordering — a 24V application would require a different lamp specification.
3. Complete Assembly (Not a Lens or Bulb Only): This listing covers the complete lamp assembly. Bulbs may or may not be included depending on the supply channel; the socket and wiring provision are integral to the assembly. Confirm bulb inclusion at inquiry.

• ✓Vehicle & Engine Coverage Verified: ISUZU 600P with 4KH1 — confirmed across factory-direct listings in German, Finnish, Danish, and Russian portals. Broader platform coverage includes NPR, NKR, NQR, NMR, NLR, ELF, VC46, FVR, FTR, JMC KY, N800, N900, N720, and N725.
• ✓Voltage Verified: 12V — confirmed by cross-reference data for the 8-97365172 family listing "Voltaje 12 V" and "Tensione 12 V".
• ✓Lens & Construction Verified: Weather-resistant, aging-resistant, UV-resistant, and high-temperature-resistant lens that resists yellowing and deformation; internal sealing structure isolates sand and dust to slow metal socket corrosion.
• ✓Dimensions & Weight Verified: Actual size 33.8 × 19.2 × 9.3 cm; gross weight 0.695 kg (per unit, reference).
• ✓Factory Number Verified: 8-97365172-LL — confirmed as the factory/tooling reference for the RH assembly.
• ✓Warranty Verified: 6-month quality guarantee.
• ✓Cross-Reference Density Verified: For the RH assembly, related references include 8973651720, 8980539400, 8980108810, and 8980539380. For the LH assembly, the primary reference is 8973651730 / 8-97365173-0.
• ✓Bulb Type and Inclusion NOT Publicly Confirmed: The accessible reference data does not clearly specify the exact bulb type (e.g., P21W, PY21W) or whether bulbs are included in the package. One cross-reference lists "Bulbo 2" and "Con el cable 4 se alza" (with 4-wire provision), but this data belongs to an adjacent reference number and should not be assumed to apply to 8-97365172-0/173-0 without supplier confirmation. Confirm bulb type and inclusion at inquiry.

• Turn signal does not illuminate: Bulb failure, corroded socket contacts, or a cracked internal reflector prevents the lamp from functioning — a direct roadworthiness and safety concern.
• Cracked or broken lens: Impact damage from road debris or minor collisions allows moisture ingress, corroding the reflector and socket.
• Moisture condensation inside the lens: A compromised lens-to-housing seal traps moisture, reducing light output and accelerating corrosion.
• Dim or discoloured light output: A degraded reflector or aged bulb produces insufficient brightness for legal compliance and safe signalling.
• Loose or detached housing: Broken mounting tabs or clips allow the lamp to vibrate or detach from the vehicle body.
• Parking / side marker function inoperative: In lamps with dual-function design, one function may fail while the other continues — both must function correctly for road legality.

• Left vs. Right is the first check: 8-97365172-0 is the RH assembly; 8-97365173-0 is the LH assembly. Do not interchange left and right.
• Voltage is the second check: Both units are confirmed for 12V. Confirm the vehicle's electrical system before ordering.
• Bulb inclusion varies: The reference data does not clearly confirm bulb inclusion. Confirm at inquiry — a lamp without a bulb cannot be returned to service until one is sourced.
• Vehicle coverage breadth: While the core application is 600P with 4KH1, the same lamp architecture is shared across NPR, NKR, NQR, and related N-Series variants. Provide the VIN for final confirmation in mixed-fleet applications.

1. Confirm the required parts first: Verify that the replacement lamps are the correct RH (8-97365172-0) and LH (8-97365173-0) units. Compare the housing angle and connector shape to the original lamps.
2. Access the lamp: On the 600P platform, the front corner lamp is typically accessed from behind the front bumper or by removing the headlamp assembly. Refer to the workshop manual for the specific access procedure.
3. Disconnect the electrical connector: Release the connector latch and unplug the lamp harness. Do not pull on the wires.
4. Remove the old lamp: Remove the mounting screws or release the retaining clips. Note the orientation of the housing and any rubber seals or gaskets.
5. Transfer or install the bulb: If the replacement lamp is supplied without a bulb, transfer the bulb from the original lamp (if serviceable) or install a new bulb of the correct specification. Do not touch the glass envelope of a halogen bulb with bare fingers.
6. Install the new lamp: Position the lamp into the body opening, ensuring the housing seats flush against the mounting surface. Install the screws or engage the clips.
7. Reconnect the electrical connector: Plug the harness connector in until the latch clicks. Verify that the seal is fully seated to prevent water ingress.
8. Test operation: Turn on the ignition and operate the turn signal and parking light functions. Confirm correct illumination and flash rate.
9. Check for moisture: After a short period of operation or a water spray test, inspect the lens for condensation — a properly sealed lamp should remain clear.

• Inspect the lamp lens at every service or every 20,000–30,000 km — check for cracks, moisture, and discolouration.
• Check the bulb and socket if the lamp fails to illuminate or flashes irregularly — corrosion in the socket is a common failure mode on older trucks.
• Clean the lens with a soft cloth and mild detergent — avoid abrasive cleaners that can scratch the polycarbonate surface.
• Replace the lamp if the lens is cracked or the housing seal has failed — moisture ingress will accelerate reflector degradation and socket corrosion.

• Standard packing: Neutral packaging or customer-branded packaging available. Confirm exact packaging configuration at inquiry.
• Package contents: 1 × Front Turn Signal Assembly (RH or LH). Bulbs may or may not be included — confirm at inquiry. Mounting screws and wiring pigtail are typically not included.
• Set options: Single lamp (RH or LH) / RH + LH pair (8-97365172-0 + 8-97365173-0) — specify at inquiry.
• Delivery time: 10–15 days (reference).
• Suitable for: ISUZU 600P / NPR / NKR / NQR lighting repair shops, commercial truck fleet maintenance departments, spare parts distributors, and export wholesalers.
