wattage on side lights
 

just wondering! just changed my headlight bulbs to arctic whites and now my side lights look poor.So i fitted some blue bulbs and these look poor:found out you can get 16watt side lights but are 11mm longer than standard:if i fit these they are a short term measure till i get a full crystal upgrade:will these cause any problems with increased wattage or additional length.ie melt plastic or drain battery etc:ant help greatly appreciated
