the title sums this up pretty well - I have a 3/4 year old police tech focus and I now have the t7, I usually use a 7 standard red led torch in conjunction with this, but I was thinking that I could put a 1w red led in the old lenser. other than changing voltage can you think of any problems with this conversion? (the led is the same size and shape.
