this is the unit i bought


i have just found a lens only. now the lens is slightly smaller than the stock uk fog light and it tapers slightly different too and would probly need to be screwed to the standard assembly and sealed with silicon to fit.
here it is.

nice cheep mod. just get a red led bulb
i have also found a front indicator that looks to be the same size housing as the reverse light so maybe buy the 2 items to give it a go.
