LED Signal & Brake Bulbs
Confirm the socket first (1156, 1157, 3157 or 7440), then choose the colour. Our LED bulbs fit turn signal, brake and tail light positions and run on 10-30V.
Signal and brake bulbs are the bulbs drivers replace most often and notice first when they fail. They are cheap to stock, easy to bundle, and a good way to add volume to an order that also contains headlights.

Fast flashing is a load problem, not a bad bulb
An LED draws far less current than a halogen bulb. The car reads that as a failed bulb and flashes fast. There are three fixes.
Add a load resistor
Brings the load back up for the car.
Fit an electronic flasher
Keeps the turn signal flashing at the normal rate.
Choose a Canbus model
Made for cars that check bulbs.
Easiest fixBrake and tail light in one bulb
A dual-filament bulb has a strong light for braking and a weak light for the tail. The table lists both outputs.

Flicker, warning light or fast flashing: what to do
Most problems with LED bulbs are not defects. They come from a mismatch between the bulb and the car’s electronics, and each one has a simple fix.
Flickering
- Likely cause
- Wrong polarity or low load
- What to do
- Reverse the plug, or choose a non-polar model such as Z2S
Bulb-out warning on the dash
- Likely cause
- The car cannot see the load
- What to do
- Choose a Canbus-ready model (V25, Z2S) or add a decoder
Turn signal flashes fast
- Likely cause
- Load too low
- What to do
- Add a load resistor or fit an electronic flasher
One side is dimmer
- Likely cause
- Loose plug or driver connection
- What to do
- Check the connectors on both sides
Pricing by quantity
Price should be easy to plan before you ask, so here is how we quote.
Rules, sealing and documents
Certificates: what is and is not covered
Importers and large buyers usually ask for documents before they order. Selected models hold CE (EMC), RoHS and PSE reports, an E-mark approval and a German EPR registration. A model that is not listed on a certificate is not covered by it. See the certifications page for the standards and the models.
Waterproofing
Headlights and fog lights live in rain, spray and dust, so sealing matters. Sealing is checked in production with a waterproof test. The IP rating of each model is on its data sheet, available on request. The 3-inch demon eye models are rated IP68.
Add volume without adding risk
Signal and brake bulbs are low-priced, small and easy to pack, so they raise the size of an order without much risk. They are also repeat purchases: when one bulb fails, the owner usually replaces the pair. The three tiers, 50-499, 500-999 and 1,000 or more pieces, make it easy to see what a larger order saves.
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.
