[Healeys] Electrical Relays for Lighting System

Folks,
 
A friend has asked  for opinions on the merits of installing relays to feed
the headlights on a Bugeye Sprite.  He read an article online that claimed
relays would decrease the amount of current going through the ignition
switch. The article stated that there is a lot of resistance in the
headlight switches that drops the voltage and creates heat, thus the switch
fails earlier, and the headlights are not as bright as they would be with
relays. The article also claimed that with the relay, the voltage goes
straight from the battery to the lights so the current carried by the switch
is lower so it last longer, and the lights are brighter.
 
I can forward the article to anyone interested.
 
Thanks in advance for y our thoughts.
 
Ron
