YOU ARE ASKING FOR TROUBLE RUNNING 17 AMPS OF CURRENT WITHOUT A RELAY !
AND, NO !, to adding more lights to the same circuit but YES !, to all four lights on one switch.
200 watts / 12 volts = 16.66 amps, that is a lot of amperage,
If I am correct all KC Day Lighters 150 w or the 100w units if sold in a pair pack have a relay in the harness, if you purchased new check with KC.
The another 9 amps for the two 55w lights… adding 9 more amps to a 17 amp circuit without a relay is a setup for a possible fire.
IMHO… Start again with the light wiring, add a relay to the 200 watt light circuit and a new fused direct power wire from the battery. this will give you brighter lights and longer lasting lights.
Then add another circuit for the two smaller lights, with its own relay BUT you can use the same switch to activate them; just jump from pin 85 on one relay to pin 85 on the next one and all will work OK.
Follow this How-To and you will have no problem with over heated wiring:
Remember 2 Lights per circuit, per Relay is the std rule,
IF you increase the wire gauge, the rating of the fuse and the Relay then you could run more lighting but why.
How-to: Aux Light Hookup with Indicator Light
Look at the schematic above posted for a quick wiring setup.
This sounds like i am preaching but believe me over heated wiring and sockets WILL lead to a fire, might not be tonight but if left on long enough it will !
