Smart Bluetooth Control for Modern Lighting Needs
Unlike basic dual-color LED bulbs that toggle yellow and white using a switch or high/low beam triggers, the APP-K13 series gives you full smartphone-based control. After installation, simply open the mobile app and adjust color temperature using an intuitive slider. From 3000K for dense fog to 6000K for clear highways, every lighting condition is addressed. The bulbs also remember your last selected color mode, so the setting stays consistent after every restart.
The app works on both Android and iOS devices, making it compatible with all modern smartphones.
True Performance with Real 200W Output
Each pair of APP-K13 bulbs delivers a real 200W output (not inflated marketing figures), offering an impressive 20000 lumens brightness. The bulbs project a wide and uniform beam pattern, improving visibility across long stretches of highway and tight city lanes. Instant-on illumination ensures you get full brightness the moment you switch on the lights, without any delay.
The dual-color functionality makes these bulbs ideal for monsoon regions, night touring, foggy roads, and daily commuting. With the ability to switch between yellow and white, you no longer need separate fog lamps or multiple lighting setups.
Premium Build Quality with Efficient Cooling
TecUpdater prioritizes durability and long-term performance. The APP-K13 bulbs are built using an aircraft-grade aluminum alloy housing paired with a high-RPM silent cooling fan. This ensures effective heat management even during extended usage.
The bulbs are IP68 rated for water and dust resistance, making them suitable for both motorcycles and cars that face harsh weather, off-road conditions, or long-distance touring. High-quality drivers regulate voltage and prevent flicker or thermal overload.

For cars like VW Polo, Vento, Rapid, Creta, City, or Baleno, the direct H7 fitment allows quick installation without disturbing the original wiring.
Safety, Reliability, and Warranty
With intelligent temperature monitoring and voltage stability management, the APP-K13 bulbs maintain consistent brightness without overheating. The sealed construction protects against moisture, dust, and engine bay heat.
Every TecUpdater bulb undergoes quality checks for beam alignment, thermal stability, and app connectivity before dispatch. The product includes a 2.5-year warranty and exchange-only return policy.

The app-controlled range ships in H4 and H7. H4 buyers may see any of the names below stamped on the original bulb.
| H4 | 9003, HB2, 64193, 12342 |
