Description
An amber WT21W lamp is easier to identify when both the socket code and colour are correct. ARC Lighting 3121A is the ECO-series LED replacement for applications calling for that exact combination.
Its compact body and diffused lens are designed for even illumination rather than a large external lamp housing. Check bulb polarity, original socket and local exterior-light regulations before replacing factory lighting.
