Taxiing to Runway 35R on Taxiway D; the ILS critical area painted markings on the taxiway are incorrect.  The markings on the ground are those of runway boundary/hold short not those for an ILS critical area. There are also wig-wag lights on and flashing at the ILS critical area and not at the actual runway boundary. These non-standard markings are very confusing. SDF needs to remove the wig-wag lights and paint the correct markings on the ground at the boundary of the ILS critical area.
B737 Captain believes that the ILS critical hold line on Taxiway D at D1 is painted incorrectly as a runway hold line at SDF.
