MCK Auto P13W LED Canbus bulbs for DRL (daytime running lights) – white, 2 pack
Product description
If you want your daytime running lights to look more modern, LED replacements like the MCK Auto P13W Canbus bulbs are designed for exactly that. They’re a simple plug-in style swap for the P13W-style bulb, with an “instant” on/off behaviour and a white output aimed at matching a cleaner, brighter daytime look.
That said, LED bulbs aren’t always a straight swap on every car. The important bit here is the Canbus angle: on some vehicles the monitoring system can react differently, which is why the compatibility note in the listing is worth taking seriously.
The essentials
These are P13W white LED Canbus bulbs intended for daytime running lights. The build described uses multiple bright chips “on the sides” plus one stronger CREE chip on top, with a diffuser to help spread the light. The practical promise is a brighter, more eye-catching DRL appearance with quick on/off once your lights are activated.
The listing also positions them as a quick replacement job: remove the old bulb and fit these in its place. No extra tools are mentioned, but access can depend on your car’s bulb location.
What you’ll notice in day-to-day use
On paper, the selling points translate to everyday visibility and a more updated look. DRLs are the lights you tend to see most during commuting and daylight driving, so a brighter white output can make your front end stand out more than the factory halogen setup.
One micro-scenario that helps you judge fit: imagine starting the car in a grey morning or in traffic where DRLs are your main “front visibility” light. With instant on/off behaviour, the lights should respond immediately when DRL control activates—useful if you’re used to how conventional bulbs feel in terms of warm-up.
The downside is that “brighter” and “error-free” can’t be guaranteed across all vehicles. Even with Canbus bulbs, some cars may still flag an issue depending on what their system expects.
Compatibility: where it fits (and where it can get messy)
The listing includes a compatibility note and several vehicle references. It mentions compatibility with cars such as A4 (B8), Q5, CX-5, i40, Sportage, and certain models/years within Mercedes E Class W212/S212/A207/C207 ranges, plus a set of Mitsubishi Outlander PHEV and Mirage examples, and some 508 SW and other models (the list is quite specific).
However, the key limitation is explicitly stated: don’t buy if your car is not listed, because Canbus current can be different on cars and some vehicles may still display an error. In that scenario, the listing says you’d need extra load resistors.
So the sensible approach is simple: double-check your exact model (and the variant/year as applicable) against the listed compatibility, rather than relying on the bulb “type name” alone.
Ease of replacement and what to check before buying
The swap is described as straightforward: pull out the old P13W bulb and insert these. The listing also notes a roughly 5-minute job and “no extra tools required”, though access depends on your car.
Before you commit, it’s worth checking a few practical things:
- Whether your car’s DRL uses a P13W-style bulb fitment in the first place
- Whether your exact vehicle appears in the compatibility list
- Whether you’ve experienced Canbus warnings with other LED replacements (some cars are pickier than others)
If you discover your car shows an error after installing, the listing suggests contacting support first rather than forcing a fix. They also mention that their list is accurate “as best they can”, but not always perfect.
Warranty and support
There’s a 1-year warranty mentioned, alongside an after-sales support approach that asks you to contact them first if any issue crops up. That’s a helpful reassurance for a purchase where compatibility can be the deciding factor.
One limitation to keep in mind: if your car isn’t on the listed compatibility, you may end up needing load resistors to deal with error warnings. That means the “value” case works best when you match the car list correctly from the start.
Pros and where it makes sense
Pros (based on the listing’s positioning):
- Designed specifically for DRL use with P13W bulbs
- White output with multiple chips plus a CREE chip and diffuser
- Quick swap described as about a 5-minute replacement
- Canbus-focused approach intended to reduce error messages
- 1-year warranty and support if you have problems
It may not suit you if:
- Your exact car isn’t listed, because Canbus current differences can still trigger errors
- You want guaranteed error-free operation with no extra parts—on some vehicles, that can be a gamble
- Your bulb access is awkward and you’re not comfortable with a DIY swap (the listing notes access depends on the car)
Should you buy it?
Buy the MCK Auto P13W LED Canbus bulbs if you’re replacing DRL bulbs that match a P13W-style fitment and your exact car is included in the compatibility list. The whole point is a quick visual upgrade with instant on/off behaviour and a brighter white daytime look, while the Canbus design aims to avoid errors.
Skip it or at least be cautious if your car isn’t clearly listed, because the listing itself warns that Canbus current can differ and some cars may still show an error (with load resistors potentially needed). For anyone chasing a guaranteed “fit-and-forget” experience, it’s the sort of purchase where checking compatibility carefully matters more than the bulb brand name.
Quick FAQ
Canbus means it will always avoid dashboard errors?
Not necessarily. The listing warns that some cars can still show an error due to Canbus current differences, especially if your car isn’t listed.
How long does the replacement take?
The listing describes it as a simple replacement job taking around 5 minutes, with no extra tools required, though access can vary by car.
What’s included in the pack?
It’s a 2-bulb pack, described as compatible with DRL applications.
What if my car isn’t listed but the bulb type matches?
The compatibility note strongly suggests not buying if your car isn’t listed. If you still go ahead and you get an error, the listing indicates you may need extra load resistors.
Metres of warranty or support coverage?
A 1-year warranty and an advice-first support approach are mentioned, with the suggestion to contact them if you have issues.
