I picked this thread at random as an LED lighting thread. I installed an LED in my '74 Aermacchi and it's enormously better than the stock sealed beam- or the more modern high output H4. But it was also very expensive. I chose it because I have only 140 watts of charging system to work with. I improved the light on my 1100 Sport by cleaning the inside of the lens; my '85 LeMans was *hugely* improved by adding a separate battery circuit and 30a relay to the H4. I haven't yet relayed the 'Sport, but I expect the same level of improvement. I don't LED.https://danielsternlighting.com/tech/bulbs/Hid/conversions/conversions.html I added headlight relays to both my '87 Lemans & '03 Lemans primarily to reduce voltage drop and improve hbar switch longevity. More recently I added H4 LED's to those bikes to reduce charging system load and improve daytime conspicuity. I'm reluctant to ride before sunrise or after sunset anymore but was caught once last Fall after sunset on the '87 with the new LED H4 and was please with the performance. Although I have no idea of how long the bulb will last ...amazon $17. So, I guess we'll see. 1 Link to comment Share on other sites More sharing options...
gstallons Posted Saturday at 01:05 PM Report Share Posted Saturday at 01:05 PM I did the relays to my 87 and wired it so both dim & bright would come on w/high beams . Link to comment Share on other sites More sharing options...

This comment actually brings something to light (I wish I'd thought that pun) that I hadn't considered; The editorial I linked to says, without saying, that an inappropriate lamp makes ineffective use of the reflector and that prevents the light 'getting where it's needed'. BUT. What if I never ride at night? What if I ride at night only in the city, or only below 45mph? I might make the argument that having more wasted light, or glare to oncoming traffic, is actually safer under these conditions. 2 Link to comment Share on other sites More sharing options...
