i figures everything out and connected them it was all proper so now i have a question is it necessary to insert the wires deep inside the breadboard

If you mean a solderless breadboard, the wires should have about 4 mm of insulation stripped from them, and should be inserted about 4 mm into the breadboard. The wire should be solid (not stranded); 22 awg is best, but 24 awg is okay, and 26 awg might work. Don't shove anything bigger than 22 awg in the connectors, or you may damage the connector.

Congratulations on figuring out the schematic.

 

No, only need a millimeter or two after you feel the resistance of the spring clips in the breadboard.

You should be using wires made for breadboards or 22 gauge solid copper wire.

Buy a spool of 22 awg solid wire and make your own. Just cut pieces of wire about 60 mm long, strip 4 mm of insulation from each end, and you have a jumper. You can also make some about 35 mm long. If you make them too long, the extra length just gets in the way and adds confusion. If you have the money, it's nice to have different colors (red for +V, black for ground, and other colors for signals), but you don't have to have more than one color. If you buy white wire, you can mark the jumpers with a dab of paint to differentiate them. Here's a photo of one of my breadboards.

[...] is it necessary to insert the wires deep inside the breadboard

Well, relatively and unless it's a brand new board, check that each wire/pin has a good connection (multimeter/Ohm-meter/continuity tester). If it has been used with larger size pins, the contact points doesn't always get fully back in shape, often leading to intermittent connections.

EDIT: Oops, just realized it was an old tread. The issue with bad contacts in solderless breadboards is still current though.

 

Students looking (probably Googling !) for traffic light circuits should make sure the design they copy works the sequence they want. In the UK for instance there is a phase where red and amber on on together. I don't think this is common but you should check that the design is correct for your country.
