Direct answer
For indicator lamp replacement, match the base, voltage, wattage, size and circuit requirement before choosing a substitute. If color, polarity, LED conversion or panel fit is uncertain, Confirm by RFQ.
Comparison table
| Check | Buyer action |
|---|---|
| Base | Match screw, bayonet, wedge, flange or wire-ended style |
| Voltage | Use the panel or machine circuit voltage |
| Wattage | Confirm brightness, heat and electrical load |
| Color | Check bulb color, lens color or LED color requirement |
| Size | Measure clearance inside the indicator holder |
How to identify
Check the old bulb base and holder.
Read voltage and wattage from the bulb or machine panel.
Confirm color requirement from the lens or machine function.
Photograph the panel holder if the bulb shape is unusual.
Buyer checks
Provide machine or panel application.
Confirm base, voltage, wattage and color.
State whether LED replacement is requested.
Confirm by RFQ for polarity, driver or circuit questions.
Confirm by RFQ
Indicator lamp replacement depends on circuit and holder design. AOTENG can review the supplied specification, but final machine compatibility should be Confirm by RFQ.
Common mistakes
Replacing an incandescent indicator with LED without checking polarity or circuit behavior.
Ignoring the holder depth.
Selecting by color name without confirming lens color and bulb color.
FAQ
Can LED replace an incandescent indicator lamp?
Sometimes, but polarity, voltage, socket and circuit behavior must be checked first.
What if the indicator has a colored lens?
Still confirm bulb color and lens color because the final visible color depends on both.
What should I send for panel lamp RFQ?
Send base, voltage, wattage, color, dimensions, holder photo, quantity and application.
