Latest WigWag 36 Pattern Light Module
The Latest WigWag 36 Pattern Light Module by Stop-Alert is designed for heavy-duty emergency vehicle use. It features 36 programmable light patterns, not just a few presets, with integrated LEDs and a dedicated program switch. The system includes solid circuits with a 20-amp flasher relay, delivering up to 10 amps per channel (240 watts total). It supports 12–24V operation and is suitable for headlights, LED arrays, and other lamps. Best for fleets that require varied signaling to adapt to different driving conditions or mission types.
Who it’s best for and why: Ideal for police, ambulance, and fire-trighting fleets that need flexible flash patterns and robust electrical performance. The two-channel design helps manage two independent light banks. Caution: complex programming may have a learning curve, and higher current draw requires careful wiring to avoid overloads.
URANT D4 Wig-Wag Dual-Channel Relay
The URANT DC 4.5-30V 10A Adjustable Alternating Flasher Relay offers dual independent timing channels with adjustable on-times from 0.01 to 15 seconds. This flexibility enables custom wig wag patterns, including asymmetrical flashing for standout signaling. Its wide voltage range supports both 12V cars and 24V trucks. It comes pre-wired with color-coded connections and mounting holes for straightforward DIY installation.
Who it’s best for and why: A good pick for technicians who want to tailor timing precisely for two separate light banks. Choose this if you need distinct, programmable intervals per channel. Caution: ensure your load per channel does not exceed 10A to maintain reliability.
Stop-Alert New X2 Wig Wagger
Stop-Alert’s New X2 Wig Wagger is a waterproof, universal wig wag strobe flasher designed for emergency fleets. It supports 12–24V operation with a robust 72W load capacity (36W per channel). The module is optimized to grab attention with alternating light patterns that drivers notice quickly. It’s compatible with headlights, LEDs, and other lamps typically found on police, ambulance, and fire vehicles.
Who it’s best for and why: Suitable for vehicles requiring a high-visibility upgrade without a complex wiring scheme. Best for standard installations where two strong light channels are sufficient. Caution: users should verify compatibility with existing vehicle lighting before integration to avoid overload.
New Wig Wag 36 Pattern Wave Wagger
This Stop-Alert model offers the same core features as other Wig Wag kits but emphasizes universal compatibility with headlights, LEDs, and other lamps, and is designed for emergency vehicles. It includes 36 programmable patterns, integrated LEDs, and a 20-amp dual-output design (10 amps per channel). It’s backed by a two-year warranty, making it a sturdy choice for fleets requiring reliability across mixed lighting setups.
Who it’s best for and why: Choose this if you need a flexible, long-term solution for mixed lighting configurations across different vehicle classes. Caution: ensure your wiring harness supports dual 10A channels without voltage drop.
Stop-Alert FastWagger 240W
The Stop-Alert FastWagger is a high-speed wig wag controller designed for urgent signaling with rapid flashing rates. It delivers up to 240W total (120W per channel) across 12–24V systems, making it well-suited for vehicles that require rapid attention-grabbing patterns. It emphasizes speed and strong visibility for critical warning scenarios.
Who it’s best for and why: Best for departments or fleets that operate in high-traffic environments where fast, aggressive signaling improves conspicuity. Caution: extremely rapid patterns may be distracting in residential or densely populated areas; use judiciously.
iJDMTOY Alternating Left/Right Strobe Box
The iJDMTOY Alternating Left/Right Strobe Flash Module Box is designed for universal fit on many cars, including JDM, KDM, Euro, and American muscle. It operates at 12V DC with a maximum current of 4A and a 48W output. The compact unit comes with wire leads at both ends, making it suitable for smaller installations like fog lights, DRLs, or work lights where space is limited.
Who it’s best for and why: Ideal for DIY installations needing a compact, low-current wig wag solution. Choose this if space is a premium and you need simple integration. Caution: power is limited to 4A per channel, which may be insufficient for high-wattage LEDs.
Buying Guide
- Voltage range and compatibility: Most wig wag modules operate at 12–24V. Confirm your vehicle’s electrical system and the module’s voltage range before purchasing to avoid mismatches.
- Current capacity: Check per-channel current (amps) and total wattage. High-power LEDs or multiple lamps require higher amperage to prevent dimming or component stress.
- Pattern selection: If you need multiple patterns, prefer modules offering 30+ patterns or programmable sequences. This supports adaptable signaling in different scenarios.
- Durability and weather rating: Waterproof or sealed enclosures are important for exterior vehicle installations. Look for weatherproof certifications or robust housings.
- Ease of installation: Pre-wired connections and clear mounting provisions reduce DIY complexity. Color-coded wires and mounting holes simplify wiring.
- Reliability and warranty: A longer warranty indicates confidence in durability. Consider a two-year or longer warranty for fleets.
- Space considerations: Compact modules save mounting space, beneficial for motorcycles or police bikes where space is at a premium.
- Safety implications: Ensure you comply with local regulations on emergency lighting usage and brightness to avoid unlawful signaling.
