第三步:安装电源（变压器或开关电源）； 根据变压器的功率以及护栏灯的功率来计算每台变压器可以带多少条护栏灯；比如108灯的LED七彩护栏灯是10W/M；144灯的LED护栏灯是12W/M；若用400W的防水变压器，则可以带108灯36M管；144灯的则带32 M管。若变压器可以带36M管；变压器则放在第18和19条中间，接两条线出来，每边各带18条。
Three major steps in the installation of LED traffic lights
The first step: the first LED guardrail lamp installation to the wall: punch a hole in the wall, installed expansion screws, re installed LED guardrail lamps, with self tapping screw lock; distance between guardrail lamps according to the requirements of customers; 1cm to 3cm.
The second step: then the signal line of LED fence lights, power lines, the signal line is generally four or five core male female plug; the power cord is the two core of the male plug;
The third step: install transformers or switch power supply; according to the transformer's power and guardrail lamp power to calculate each transformer can take many a guardrail lamps; 108 light colorful LED guardrail lamps, for example, is 10W/M; 144 lamp LED guardrail lamp is 12W/M; if with 400W anti transformer water, with 108 lamp 36m tube; 144 lamp, with 32 m tube. If the transformer can be with 36M tube; transformer is placed in the middle of the eighteenth and 19, then two lines out, each side with 18.
