Two switches to two separate lights

I plan to install 2 roof lights and want to install 2 swithces, one for each light. I have the power source coming to the first fixture (light) box it is 14/2. I plan to power the first switch from there and then power from switch to fixture. How do I uses the same 14/2 cable to power the second indipendent switch and light? I do not want the first switch to control the 2nd switch or light? Do I have to use a 3 wire or can the 2 wire do it?

Let's see if I have this right (I'm a newbie) ...

You want to run:
Power -> Light 1 -> Switch 1
Switch 2 -> Light 2

-- Using only 14/2, can you run 14/2 from L1 to L2 and drop another 14/2 to the switch?
-- Otherwise, it seems that you'd have to run 14/3 between L1 and S1 (red wire) so it also carries power (black wire) to S2 and L2.

IF the 2 switches are in the same box follow this procedure------run a 14/3 cable from "Lite #1" (L#1) to the switch-box.-----Cover the WHITE wire of the 14/3 cable with Black electrical tape at BOTH ends-----at the switch-box the White-marked-Black will connect to one terminal of one of the switches and then "jump" to one terminal of the other switch- both switches are now connected to the W-m-B wire.----connect the Red wire to the "spare" terminal of one of the switches and the Black wire to the "spare" terminal of the other switch-------run a 14/2 cable from "L#1" to "L#2"------at "L#1" connect the W-m-B of the 14/3 switch cable to the Black of the 14/2 "feed" cable----connect the White of the 14/2 "feed" cable to the White of the 14/2 cable to "L#2" and the White fixture lead to "L#1"----connect the Black wire of the 14/3 switch cable to the Black of the 14/2 wire to "L#2"-----connect the Red wire of the 14/3 switch cable to the Black fixture lead of "L#1".----Good Luck!!!

Thanks for replies. So far I gather that I will have to place a 14/3 somewhere in the loop. The 14/2 alone will not complete the job.

I should have told you that the switches are at different locations so there has to be an adjustment to the last reply. Could you state how I make the connection with the switches at different locations?

The trouble with answering these questions is that you have so many options. It's difficult to provide detailed instructions for each of a dozen options. We don't really know what would be easiest for you because we can't see the topology.

Let me offer just a few. Not all involve the use of 14/3.

(A) Power on 14/2 to L1. 14/3 from L1 to S1. 14/2 from S1 to S2. 14/2 from S2 to L2.

(B) Power on 14/2 to L1. 14/3 from L1 to S1. 14/2 from S1 to L2. 14/2 from L2 to S2.

(C) Power on 14/2 to L1. 14/2 from L1 to S1. 14/2 from L1 to L2. 14/2 from L2 to S2.

(D) Power on 14/2 to L1. 14/2 from L1 to S1. 14/2 from L1 to S2. 14/2 from S2 to L2.

(E) Power on 14/2 to S1. 14/2 from S1 to L1. 14/2 from S1 to S2. 14/2 from S2 to L2.

(F) Power on 14/2 to S1. 14/2 from S1 to L1. 14/2 from S1 to L2. 14/2 from L2 to S2.

There are many other possibilities. I'm hoping one of the above will suit you. Pick one and we can provide the connection information.

14/2 is OK

Your not running 3 way switches just a SPST. Power comes to the 1st switch box with a black and white 14/2. Run a 14/2 to the 2nd switch box.Now wirenut a black 6" pigtail wire to the incomming power( black line ) and the black line going to switch #2,. Connect the black pigtail wire to switch one on one side. Run a 14/2 to the light and connect the black wire going up to the light, to the switch. White wires are to the neutral, on the #1 light connect the black to the brass screw, the neutral white wire to the silver screw. Light one is done. Now the three black wires are connected togetherone is a feed, one is a pigtail and the third goes to light two. The white is pigtailed all together with the other white wires. now you have a hot and neutral feed going to your 2nd light switch. The black goes to one terminal of the switch. Run a 14/2 to the light. Connect the white wires together at the switch. The black wire going up, goes to the 2nd terminal of the light switch. Now the light connections are connected in the same fashion as the other one was.
Simple!!!
All with 14/2
Remember to wire in the ground wire to both the switch ( green screw ) and the box if (it's metal). Also, wirenut all the white wires together..at each box, first thing.

Thanks
Nelson the one at C looks the best since the first power come to the fixture box and then to switch. Note the swithces are independent
PATBAA and HVAC 01253 I will also look at you options. However PATBAA yours seems need to look at the swithes separately.

Bye

Okay. Option C it is. All 14/2.

Power to L1: "P"
L1 to S1: "X"
L1 to L2: "T"
L2 to S2: "Y"

At L1:
(1) Pb to Xw to Tb.
(2) Xb to L1b.
(3) Pw to Tw to L1w.

At S1:
(1) Xb and Xw to the two screws on the switch.

At L2:
(1) Tb to Yw.
(2) Tw to L2w.
(3) Yb to L2b.

At S2:
(1) Yb and Yw to the two screws on the switch.

Remark both ends of Yw and Xw with a black marker. Connect all ground everywhere.

2 switches to two separate lights

I finally got it. Thanks Nelson, HVAC01453 and PATTBAA all of you were very helpful and I understand it now. First let me give the layout. the first switch was at the entry door then the light, then second light and the second swithch.
The power souce came into the first light box. I pigtaile the black to the black of the first switch. I then returned to the first light with the white colored black from the first swithc to the first light black to give it power. The white from the source I pigtailed to the white of the light. First light and switch finished.

At the first black pigtail in the light box I connected the black to the black fo the cable to the 2nd lamp (do not connect to fixtere)pigtailed it to the cable to 2nd switch. Brought white "colored black" from 2nd switch to 2nd lamp for power and attach to fixture black. I picked up the neutral white from the first lamp box and connected to the 2nd lamp. All with 14/2.
Thanks
