581 PY21W Ring Vision 24 indicator bulb.

• Lasts up to 3 x longer than a standard 581 bulb
• Improved filament technology
• Improved resistance to voltage variations
• 12 month warranty

The 581 Ring Vision 24 is a perfect upgrade for those who want to reduce the hassle of having to change a bulb. They have been specifically designed to last up to 3 x longer than a standard bulb which means you don't have to replace them so often. The 581 bulb is the most common indicator bulb and due to the constant on/off nature of an indicator bulb, it is one that often needs replacing. Replacing an indicator bulb can sometimes be a bit tricky due to restricted access. Therefore fitting a long life bulb would be a very practical solution to reduce the frequency of bulb changes.

The Ring Vision 24 bulb is constructed with improved filament technology which allows it to last longer than a standard bulb. It is also much more resistant to any voltage variations you get with an old or poorly charged battery.

Free UK shipping available for all orders over £25, and only £2.50 for orders under £25.

If you need your order urgently, we also have next day priority shipping for only £5.55.
