Keiurot BA9S T4W LED Bulbs 64111 1895 (9–60V) Red Pack of 2
Product description
The essentials
If you’re swapping out interior or small indicator-style lights, the Keiurot BA9S T4W LED bulbs are the sort of upgrade that can make day-to-day driving look a bit cleaner. They’re built for BA9S-type fittings (including T4W and 1895 positions mentioned in the listing) and are designed to run on DC9–60V. On paper, that wide voltage range is the main thing that makes them flexible compared with bulbs that only suit a narrower setup.
They’re also presented as low temperature and low power, which is a sensible direction for car interior/courtesy lights where heat build-up can be annoying. That said, LED replacements can be a bit of a mixed bag in real cars because warning systems vary—so it’s worth paying attention to the “canbus error free” claim and the note about some vehicles still needing a resistor/relay.
Key features that matter in practice
The listing positions these Keiurot BA9S LEDs as a brighter-than-incandescent replacement, using 11SMD 3020 chips. It also gives a brightness figure of 330LM*2, which suggests they’re trying to match (or exceed) what you’d expect from standard bulbs for visible interior lighting.
Another practical point is installation: the bulbs are described as plug and play and easy to fit. The base type is BA9S, and the colour is listed as red—so you’re not buying these for white parking/reverse light output. Instead, they’re aimed at red applications such as dome/courtesy/side functions where a red lens or red output is what you’re after.

What stands out
If you’re trying to replace small bulbs for interior, courtesy, or similar positions, these are fairly straightforward to choose because the listing spells out the socket types they’re intended to replace (BA9S, BA9, and a range including T11/T4W/53/57/1895/64111 and others).
Where they tend to make sense is when you want a red LED look for cabin/side functions, and you also want to avoid fiddly add-ons during install—because the bulbs include built-in canbus load resistors to help prevent dashboard/OBC error codes on European vehicles.
Limits and things to double-check
Here’s the part that could trip people up: LED bulbs don’t always behave the same across every car’s bulb-check system. The listing explicitly says some cars may still need a load resistor or a flash relay to prevent hyper flashing or errors. So if your priority is “no warnings, no messing around”, you may still need to be prepared for a follow-up fix depending on the vehicle.
Another limitation is positioning and output: these are red-colour bulbs, so they won’t suit people looking for white parking, reverse, or brake light-style illumination where colour output matters.
Who it’s for (and who should skip it)
It’s a good fit if you’re replacing a BA9S dome/courtesy/map/cargo-type bulb position (or other applications listed) and you specifically want red LED output, with plug-and-play convenience and canbus resistors already built in.
It may not suit you if your car is known to be picky with LED bulb replacements, or if you’re trying to convert a socket that needs a specific non-red colour output. It might also be a frustration if you’re not able to confirm the exact bulb size/fitment before buying—because the listing asks you to check compatibility details first.
A micro-example: if your side door/courtesy lamp has a small BA9S-style bulb that turns on when you open the door, swapping to this pack of two could give you a brighter red cabin cue without needing tools—assuming your car accepts the LED and doesn’t throw up warnings.
Is it worth it?
Worth considering if you have a BA9S/T4W/1895-style bulb position that’s currently using incandescent bulbs and you want a red LED replacement with a wide DC9–60V input and built-in canbus load resistors to reduce the chance of OBC errors.
You may want to skip it if the goal is non-red light output (e.g., white parking/reverse lighting), or if you’re buying without confirming the exact socket size and part number match. Also, keep in mind that “canbus error free” is still caveated—some vehicles may require extra components to fully prevent hyper flash or warnings.
Mini FAQ
FAQ
Are these BA9S bulbs red or white?
They’re listed as red-colour bulbs, so you should choose them for red lens/output positions rather than white illumination.
Do they have built-in canbus resistors?
Yes, the listing says they come with built-in canbus load resistors to help avoid OBC error codes on European vehicles, but it also notes some cars may still need an additional load resistor or flash relay.
Are they plug and play?
The bulbs are described as plug and play, with easy installation and no tools required.
What voltage do they run on?
The DC input range is listed as 9–60V.
What’s included in the pack?
The package includes 2x BA9S LED T4W 9–60V red bulbs.
