How to install
Fitting an LED bulb follows the same steps as changing a halogen bulb, with one extra job: finding a place for the driver or heat sink.
Switch the lights off and let the lamp cool.
Open the lamp cover and remove the old bulb.
Check there is room behind the lamp for the heat sink and driver.
Fit the LED bulb and plug in the connector.
Fix the driver in a safe spot, close the cover, and check the beam on a wall.

Why resellers buy signal bulbs from TUHO
You deal with the factory
We make the product in Dongguan, in a 5,000 sqm automated plant with a capacity of more than 5 million units a year. Questions about specifications, changes or timing go to the people who build the product, so you get a direct answer, not a relay.
Packed to sell
Neutral color boxes are standard, and custom boxes, labels and barcodes can be added to match your shelf or your marketplace listing. Carton sizes and weights are fixed in the catalog, so shipping is easy to plan.
Start small, grow when it sells
The minimum order is one carton: 50 sets for most V-series bulbs and 20 sets for the X series. You can test a model in your market before you commit to a larger order.
Checked at every step
Every order passes raw material inspection, an aging test, an extreme-temperature test, a lumen test and a waterproof test, then a full inspection of function, appearance and labeling before packing. Problems are caught in the factory, not by your customers.
