The physical length of the Lucas ceramic type of fuse is either 1 inch or 1.25 inch, with conical ends. Lucas Glass tube fuses have straight ends. Lucas type fuses usually use the same color-coding for the rated current. Lucas fuses have three ratings; the continuous current they are designed to carry, the instantaneous current at which they will fuse, and the continuous current at which they will also fuse. The figure found on Lucas fuses is the continuous fusing current which is twice the continuous ampere rating that the system should be using; this can be a source of confusion when replacing Lucas fuses with non Lucas fuses. The Lucas 1/4" diameter glass tube fuse have a different length as compared to the standard US item. The Lucas 1/4" diameter glass tube fuse is 1 and 5/32" [≈29.4 mm] long, while the US standard 1/4" glass tube fuse is 1 and 1/4" [≈32.0 mm] long. However many Lucas fuse holders permit the longer U.S. version to be installed easily.</p><h3 style="color: rgb(0, 0, 0); background-image: none; background-position: initial; background-size: initial;

<div>Could the color be oxidation of some sort. Copper will go
green. The proper fuses are inexpensive. I'd just get some
new ones. Get them from a British parts supplier as they are
rated to a different standard than American ones.</div>
