電動車LED燈的(de)三根線(xian)，通(tong)常為遠光線(xian)、近光線(xian)和負極線(xian)，需分別對應連接(jie)到原車相(xiang)應線(xian)路(lu)上(shang) 。

在連(lian)接(jie)這三根線(xian)(xian)(xian)(xian)(xian)之前，要(yao)先明確(que)它(ta)們各(ge)自的功能和(he)走向。一般來說，負(fu)極(ji)線(xian)(xian)(xian)(xian)(xian)顏色(se)和(he)喇叭線(xian)(xian)(xian)(xian)(xian)、轉向燈(deng)線(xian)(xian)(xian)(xian)(xian)相(xiang)同，且這幾根負(fu)極(ji)線(xian)(xian)(xian)(xian)(xian)至少有三根顏色(se)一樣，它(ta)要(yao)接(jie)原(yuan)車(che)負(fu)極(ji)。遠光(guang)線(xian)(xian)(xian)(xian)(xian)和(he)近光(guang)線(xian)(xian)(xian)(xian)(xian)則(ze)分別(bie)接(jie)原(yuan)車(che)對應的遠光(guang)和(he)近光(guang)線(xian)(xian)(xian)(xian)(xian)路。由于三輪車(che)是正(zheng)(zheng)(zheng)控，用正(zheng)(zheng)(zheng)極(ji)控制(zhi)燈(deng)，所以(yi)在找到負(fu)極(ji)線(xian)(xian)(xian)(xian)(xian)后(hou)，要(yao)關閉轉向燈(deng)、打(da)開大(da)燈(deng)并切換遠近光(guang)，通過(guo)用正(zheng)(zheng)(zheng)極(ji)線(xian)(xian)(xian)(xian)(xian)試(shi)燈(deng)來找到正(zheng)(zheng)(zheng)確(que)線(xian)(xian)(xian)(xian)(xian)路。

另外，如果不(bu)確定如何(he)連接，千萬不(bu)要盲目操作。因為(wei)線接錯可能導致LED燈(deng)(deng)不(bu)亮(liang)，甚(shen)至燒(shao)毀其他部件(jian)。要是自(zi)己動(dong)手能力不(bu)強，建議將電動(dong)車及(ji)LED燈(deng)(deng)帶到就近的(de)維修站點，讓專業師傅幫忙接線。同(tong)時(shi)，市面上常見電動(dong)車電壓有48v、60v和72v ，安裝LED燈(deng)(deng)時(shi)要保(bao)證其驅(qu)(qu)動(dong)輸(shu)出電壓與(yu)電動(dong)車電壓匹配，以(yi)免燒(shao)壞驅(qu)(qu)動(dong)。總之，連接電動(dong)車LED燈(deng)(deng)三根線需謹慎，確保(bao)安全與(yu)正確。
