The YG9622720001 Side Marker Light is installed on the sides of SINOTRUK Sitrak trucks to indicate vehicle length and height to other road users. It emits an amber light (front side) or red light (rear side) depending on placement, in full compliance with international regulations. The housing is made of UV-stabilized polycarbonate with a chrome-plated bezel, offering excellent weather resistance and impact strength.
Each YG9622720001 unit features a sealed lens-to-housing bond that prevents moisture ingress (IP67 rating). The lamp is available with either a 12V or 24V LED module or a replaceable 5W wedge bulb (W5W). The LED version consumes only 0.5W while providing 15 lumens of output, ideal for modern trucks where power efficiency and long life are critical. The YG9622720001 is a direct replacement for the original side marker lights on Sitrak C7H, T7H, A7, and HOWO T5G series.
Using genuine YG9622720001 side marker lights ensures that the light output meets legal minimums for nighttime conspicuity. Aftermarket lights often have poor beam patterns or fade quickly due to low-grade plastics. With a lifespan of over 50,000 hours for the LED version, this OEM lamp reduces maintenance frequency and keeps your fleet compliant with roadside inspection requirements.
LED version produces 15 lm at 6000K color temperature. The wide-angle lens (180°) ensures visibility from all side approaches, reducing blind spots.
Fully sealed against dust and temporary immersion. Withstands high-pressure washing and road spray, common in wet climates.
Works on 12V and 24V systems without modification. Suitable for both standard and military-spec Sitrak electrical architectures.
Markings ECE R91 (amber) and SAE J592e. Compliant for international transport, including EU, USA, and Australia.
The YG9622720001 Side Marker Light is designed to fit the factory mounting holes on Sitrak C7H, T7H, and A7 truck cabs and trailers. Typical positions include: front side fenders (amber), rear side chassis rails (red), and mid-ship along the cargo box. The lamp comes with a rubber grommet and two self-tapping screws for easy installation. The electrical connector is a standard two-pin Deutsch or AMP style, compatible with most Sitrak wiring harnesses.
For older Sitrak models originally equipped with incandescent side markers, the YG9622720001 LED version is a direct upgrade that reduces current draw by 90% and eliminates bulb replacement. No additional resistors are needed because the lamp’s internal driver handles voltage fluctuations. The light housing dimensions are 115mm (L) x 45mm (W) x 30mm (H), with a 90mm screw center distance, matching all original cutouts.
Fleet operators often replace all side marker lights simultaneously with YG9622720001 to ensure uniform brightness and color. The UV-resistant lens does not yellow or haze even after years of exposure to sunlight, maintaining a professional appearance. For trucks operating in extreme cold, the LED version lights instantly without warm-up time, improving safety during winter months.

* Specifications apply to LED variant. Bulb-based version uses a standard W5W (wedge) bulb, 5W, 50 lm, lifespan 1,000 hours. Always verify your truck’s voltage before installation.
Replacing a damaged side marker light with the YG9622720001 is straightforward. Disconnect the truck’s battery to avoid short circuits. Remove the two screws holding the old lamp, then unplug the connector. Clean the mounting surface and apply a small amount of dielectric grease to the connector pins. Install the new lamp, ensuring the rubber gasket is properly seated. Reconnect battery and test function. The LED version should illuminate instantly with no flicker.
Regular inspection is key: check for cracked lenses, water inside the housing, or dim output. If the YG9622720001 fails, it is usually due to impact damage rather than electrical failure. The LED module is non-replaceable; replace the entire unit. For bulb-type units, simply replace the W5W bulb. However, upgrading to the LED version eliminates future bulb changes. Keep spare YG9622720001 lamps in your truck’s emergency kit for quick roadside replacement.
For fleets, implementing a monthly lighting check using a simple checklist can identify failed side marker lights early. Because the YG9622720001 is a legal requirement in most countries (especially for vehicles over 6m length), having all lights functional avoids fines and improves safety. The LED version’s long life means lower total cost of ownership despite higher initial cost. Many insurance companies offer small discounts for trucks equipped with LED side markers due to reduced accident risk at night.
Counterfeit side marker lights often use non-UV stabilized polycarbonate that turns yellow and cracks within one year. Their sealing is inadequate, leading to internal condensation and electrical shorts. Genuine YG9622720001 lamps undergo 1,000 hours of UV exposure testing and 500 hours of salt spray testing to ensure longevity. The LED driver includes over-voltage and reverse polarity protection, preventing damage from jump-start incidents.
Another advantage of genuine parts is the exact color match to factory lighting. Aftermarket lamps may have slightly different amber or red hues, which can look mismatched on a fleet of trucks. The YG9622720001 produces consistent chromaticity coordinates within ECE tolerances, ensuring all side markers appear identical. This attention to detail enhances the professional image of your fleet.
Finally, genuine Sinotruk parts come with a 12-month warranty against manufacturing defects. When you purchase YG9622720001 from an authorized distributor, you receive traceable documentation. For international operators, having genuine parts simplifies customs clearance because the packaging includes ECE approval marks. Protect your investment and your safety record by always specifying OEM side marker lights.
The YG9622720001 Side Marker Light is a small but crucial component that enhances the visibility of your SINOTRUK Sitrak truck. With robust construction, excellent light output, and full regulatory compliance, this OEM lamp ensures you stay safe and legal on every journey. Upgrade to genuine YG9622720001 for reliability that aftermarket parts cannot match.
