How to connect the trailer lights?
Identical number of contacts in the socket and plug
Car lamps are connected in the vehicle through contacts to a special socket. Before connecting the lights to the trailer, it is necessary to make sure that the number of contacts in the socket and the plug is identical. This is an important, because each of the contacts is responsible for the proper operation of a specific function of the connected lights. It should be selected the appropriate plug for the socket so that the number of contacts is the same. The correct plug will be easily connected to the socket. After connection of the lights, you have to get into the car, turn the key until the battery starts transferring current to the electrical system. Then you should check that all control lights on the dashboard are on. We must also check whether any of the contacts is not burnt out. The trailer must be equipped in the full set of lights and each lamp should work properly. First, you should turn on the brake light, then turn on signal lights and finally the fog lights. In the event of any lighting failure, we must find the fault and correct the contacts to ensure that all trailer lights work properly again.
Color and numerical symbols
To make the lights connection process easy and quick, the plugs with the input socket are similar in color to the contacts. You can then easily find the contact that is not working properly. In addition to colors, numerical markings symbols are also used. It is assumed that the contact of the left turn indicator has yellow color and its numerical symbol is L1. The color of contact of the fog lamps is blue, and its symbol is "+". The white color indicates the contact for the mass and its symbol is 31. The green contact with P4 symbol is for the right direction indicator. The brown contact with 58P symbol is for the right position light. The black contact with 58L symbol is for left position light. The red contact with 54 symbol is for break light.
Connecting the lights to the trailer is not a difficult task. First of all, the connection should be carried out taking into consideration all safety rules. However, if any problem occur during connecting the lamps with the use of contact sockets and if the contacts burn out, we should definitely go to the electrical specialist. Lack of knowledge of the operation of wiring systems can be a great danger.
What lights must trailer be fitted with?
Position lights are essential lamps in the trailer. Rear lights should also be connected. If the width of the trailer is greater than 1.6, then it must also be equipped with front lamps. Obligatory lights on the trailer are direction indicators. The basic lights also include brake lights, emergency lights and rear fog lights. If the width of the trailer is greater than 2.1 m, it is necessary to use front and rear clearance lamps. In addition, it is important to equip the trailer with the necessary front and side reflectors. There should be warning triangle in the rear part of the trailer. Lights must be properly fixed. The lamps should be made from high-quality materials, because the lamps are constantly exposed to external factors - e.g. adverse weather conditions (strong wind, rain, hail, snow, intense sunlight, low and high temperatures).
