Wellglass Indicator Lights can be supplied, complete with tungsten bulbs and brackets.  When units are located in a remote position, the light draws attention to the safety shower and illuminates the operating area.  If required, MBF/U (Mercury) lights or fluorescent lights can be supplied.  Alternatively wellglasses/diffusers can be supplied in green for high resolution, (the optional indicator lights fitted on the models in this range are not wired to a junction box).
