febi bilstein 37198 Reverse Light Switch with seal ring (pack of one)
Product description
If your reverse lights are flaky or not coming on reliably, a simple switch is often where you start. The febi bilstein 37198 reverse light switch is designed as an original-style spare part and includes a seal ring to help keep the connection protected.
On paper it’s a straightforward replacement, but the important bit is fitment. With vehicle electrics, even a “small” part needs the right thread and connection layout—so it’s worth doing the vehicle ID check before you order.
Key takeaways
This is a reverse light switch replacement from febi bilstein, supplied as a single part with a seal ring.
It’s set up with an M16 x 1 external thread and a 22 mm wrench size, and it has 2 connections. The colour is listed as black, which is handy if you’re trying to match the original appearance during a repair.
The essentials
A reverse light switch is one of those parts you rarely think about—until it stops doing its job. When you engage reverse, the switch should make an electrical contact at the right moment so the rear lights come on. If they don’t, or they only work sometimes, swapping the switch can bring back proper visibility and signalling.
What makes this one stand out slightly (in terms of everyday practicality) is the seal ring. That matters because reverse switches live in the sort of locations where road grime, moisture and general exposure can be an issue. A new seal can help when the old one has hardened or worn.
That said, this won’t fix every possible fault. If there’s a wiring issue, a fuse problem, or corrosion further up the circuit, replacing just the switch may leave you chasing the root cause.
Worth noting: the listing asks you to use your vehicle identification to confirm compatibility and to observe any restrictions. That’s not just legal housekeeping—reverse light switches can differ even across similar cars.
What’s included and what to check before you buy
The pack is described as a single switch (“pack of one”). The listing also references the seal ring as part of the product.
Before buying, double-check: - Thread and mounting details (M16 x 1 external thread, 22 mm wrench size are listed) - The number of connections (2) - Your vehicle compatibility using the vehicle ID check mentioned in the listing - Any fitment restrictions the retailer lists for your specific car
If you’re planning DIY fitting, the “12 month, 12,000 mile warranty” mentioned in the listing is at least something to have in mind for coverage expectations.
Where it shines
This is a sensible choice if you’re diagnosing a reverse light issue and you want a replacement part that’s intended to match original equipment quality standards “for comparison purposes”, using the same-style approach as an OEM spare.
It also tends to suit people who prefer to repair rather than replace the whole loom or start swapping multiple components without clarity. If your reverse lights fail consistently when you select reverse (rather than when the car is bumped or the weather changes), a switch replacement is the cleaner first step.

For which cars it’s described as suitable
The listing provides a compatibility range for various Ford and Volvo models (with model years shown). It also includes OE numbers “for comparison purposes only”.
You should still rely on the vehicle identification check, because “suitable for” lists are only as accurate as the data used and can vary by specification.
Examples from the list include Ford models such as C-MAX (03/07), Focus (04/06/08/99), Galaxy (06), Mondeo (01/97), S-MAX (06), Streetka (03), Tourneo (02), and Transit (02). Volvo models mentioned include C 30, S 40 II (and S 40 II AWD), S 80 II, V 50 (and V 50 AWD), and V 70 III.
Is it worth it?
It makes sense if you’re looking for a direct reverse light switch replacement and you can confirm compatibility for your specific vehicle using the vehicle ID check. The included seal ring is a practical detail for longevity where moisture and dirt are part of daily life.
You may want to skip it if you’re not sure whether the problem is electrical (for example, if the fault is intermittent in a way that points to wiring, a connector, or a fuse). In that situation, you could end up replacing a component that isn’t actually the cause.
Also keep in mind the listing’s note that specialist fitting equipment may be required—so if you’re relying on a basic tool kit, make sure you’re comfortable with the access involved.
Final verdict
For a repair focused on getting reverse lights working properly again, the febi bilstein 37198 is a reasonable “start with the switch” option—especially because it’s supplied with a seal ring and matches clear mounting details (M16 x 1, 22 mm wrench size, 2 connections). Just don’t rush past the compatibility check, because that’s the one step that can save you a lot of hassle.
