其實我一直想讓大家認識,霧燈的實際效用是什麼。
後霧燈就不用說了,大雨大霧情況下,開後霧燈可以提供後車足夠的辨識度,避免追撞。
那麼前霧燈呢?

在濃霧的狀況下,開起近光燈或是遠光燈,都會直接被霧所反彈回來,而對駕駛造成炫光的
影響;原廠設計的前霧燈,照射角度低,在地面離地高度30公分左右,不會聚集霧氣,前霧
燈就是利用這個特性,巧妙地避開濃霧來提供那微薄的照明。

可以看到地上那片強烈的反射光束就是霧燈照地反彈的。
雨天地濕的情況下,前霧燈由於照射角度很低,照地反射的光束會比開車頭燈提供對向車的
辨識度還高很多
以下照片為例
只開日行燈

只開大燈

看出來了嗎…霧燈反射角度提供辨識的光源比大燈還顯眼
