An indicator in a flat 238 mm strip just 10.4 mm deep — a dark bar when off, amber across the full length when lit. Tinted polycarbonate lens, IP6K9K sealing, ECE R6 and R10.06 approval, 3 m cable and a 5-year Strands warranty.
An indicator usually gives away where it is long before it flashes. This one does not: 10.4 mm of depth and a tinted lens make it read as a dark trim strip when off, not as a lamp stuck onto the body.
Switched on, amber comes out of that strip across the full 238 mm. A horizontal line instead of a dot — easier to read from the side and from behind than a single round lens, so the driver behind you does not have to guess which way you are turning.

Function indicator | Depth 10.4 mm | Approval ECE R6 · R10.06 |

Dark Knight Slim 238 mm is three lamps in an identical housing with the same 213.4 mm mounting spacing: the indicator (this lamp), the rear position light and the combined tail and brake light. Side by side they form an even row of three identical strips — switched off they look like one piece of trim, and only differ once lit.

| Guidance | Detail |
| Cleaning | lukewarm water and an alkaline degreaser; avoid pressure washers |
| Breather vents | keep free of moisture and debris |
| Internal condensation | normal; clears through the vents within a few days |
| After switching off | wait 30 minutes before touching the casing |
| Cable | do not shorten below 50 cm; make every connection watertight |
For bodies, trailers, car transporters and pickups with a flat rear face, where a conventional indicator standing several centimetres proud either does not fit or simply spoils the line. It also works along the sides of longer bodies as a clearly visible repeater.

Is the price for one lamp?
Yes, a single unit. A symmetrical installation needs two.
Does it work on 24 V?
Yes, the supply range is 10–32 V DC.
Does the tinted lens reduce the output?
The lamp holds ECE R6 approval for the indicator function in this lens version, so its photometric performance meets the regulation.
Does it match the other Dark Knight Slim lamps?
Yes — the same 238 × 20.6 × 10.4 mm housing and the same 213.4 mm mounting spacing as the position light and the tail/brake light in this range.
How long is the cable?
3 metres. The manufacturer asks you not to shorten it below 50 cm.
What is the warranty?
Five years under the Freedom Warranty programme. The manufacturer requires you to keep the manual, the purchase invoice and the batch number to claim it.
