I say this 'cos when i sold my wifes truck to Frontycustoms the first thing he did was connect up the two wires and the LED's lit up...... i had it for 12 months and never looked atthe washer jets so from this i can say it is not obvious that you have the LED washers fitted, well i never knew anyways.
Hope this helps
