I used oval 6", clear lens, amber LED's. You could use resistors to correct the problem if you like electrical fires. Resistors dissipate the excess load they are creating in the form of heat...heat that can and will eventually break down the insulation on the surrounding wires and one day... your rig is on fire!!!!!
The relay swap is just a safer way to do it and it only costs 20 bucks and takes like 15 seconds to put in.
