Miniature & Indicator LED Bulbs Series
Miniature LED indicator bulbs (T3-1/4, T5, BA9s) for dashboards, panels and signal lights. Factory direct wholesale, OEM/ODM.
Miniature & Indicator LED Bulbs: BA9s / T4W / E10 / BA7S Dashboard & Panel Light Replacements
Miniature indicator bulbs light instrument clusters, pushbuttons, and panel lamps across vehicles and industrial equipment. They use compact bases — BA9s / T4W bayonet, E10 screw, and BA7S bayonet — in ultra-short 23–25mm bodies for tight spaces. MIDCARS manufactures these in-house with discrete voltage versions from 6V up to 240V, plus frosted, diffused, and shatterproof PC-cover options.
Base Types We Cover
| Base | Type | Common use |
|---|---|---|
| BA9s / T4W | Miniature bayonet | Dashboard, pushbutton, panel indicator |
| E10 | Miniature screw | Flashlight, indicator, appliance lamp |
| BA7S | Miniature bayonet | Dashboard and gauge indicator |
How to Choose the Right Indicator LED Bulb
- Confirm the base. BA9s bayonet, E10 screw, or BA7S bayonet — read the old bulb or check the socket.
- Check the length. Ultra-short 23–25mm bodies fit low-profile pushbuttons and tight clusters; standard lengths suit open fixtures.
- Voltage. We build 6V, 12V, and 24V versions, plus discrete higher-voltage options up to 240V for industrial panels.
- Lens finish. Frosted and diffused lenses soften output; shatterproof PC covers suit high-vibration equipment.
Common Applications
- Dashboard and gauge clusters
- Pushbutton and panel indicators
- Warning and status lamps
- Flashlights and handheld lamps

What is the difference between BA9s and E10?
BA9s is a miniature bayonet base that pushes in and twists to lock, while E10 is a miniature screw base that threads in. They are not interchangeable — match the base to your socket.
Do you offer frosted indicator bulbs?
Yes. Frosted and diffused-lens versions soften the light for a clean, even glow, while clear PC-cover versions suit applications where a sharper beam or extra durability is needed.
Can I get higher-voltage versions for industrial panels?
Yes. In addition to 6V, 12V, and 24V versions, we build discrete higher-voltage options up to 240V for industrial control panels and equipment.
What is your minimum order quantity?
Standard stock starts from 5 pairs for testing. For custom packaging, the packaging run has a 5,000-piece MOQ, pre-funded and drawn down across repeat orders. Contact sales02@zhishanled.com for a quotation.
