Title: Want to replace light bulbs with LED's
Post by: analogman on March 16, 2016, 03:54:42 PM: The first time I owned this bike I installed the running light mod which replaced the sockets and bulbs for the turn signals. They were single filament bulbs, they are now 2 filament bulbs. Now, I'd like to replace them with LED's. Anyone know of a kit or how to modify these t to support LED's and maintain the running light/turn signal functions? Same goes for the tail light as well as the MOTO lights.

Post by: rbm on March 17, 2016, 10:28:35 AM: Leds are directional and only appear bright within a small arc, such as direct on.

Post by: tsnap on March 17, 2016, 11:45:36 AM: Ibelieve this to be true.

#2057 bulbs are brighter, and function the same.

I switched them out on my old chevy G20 truck, and they are brighter and work fine, but a more sensitive electrical system may produce different results.

Post by: TimTyler on March 17, 2016, 02:32:04 PM: I've recently jumpered/bypassed the terminals on the Bulb Monitoring Unit, but what is the downside to just removing the BMU without the terminal jumpers?

. . . but what is the downside to just removing the BMU . . .
Increasing the chances of having a Chatty Kathy ram you from behind because traffic had slowed down and you didn't realize your brake light wasn't working. Sometimes, though, nothing will stop Kathy when she's on her phone except impact.

Post by: TimTyler on March 17, 2016, 02:53:26 PM: Since I'm running LED's everywhere I thought the BMU was not able to check those anyway?
Title: Re: Want to replace light bulbs with LED's
Post by: Laitch on March 17, 2016, 02:55:33 PM: I think you're right, Tim.
Title: Re: Want to replace light bulbs with LED's
Post by: TimTyler on March 17, 2016, 03:03:03 PM: Yeah - I should correct my earlier post...

I didn't jumper the BMU, I removed the BMU and jumpered the BMU socket (which has the same effect as this image)

(http://www.kbikeparts.com/classickbikes.com/ckb.tech/0.ckb.tech.files/bmu/bmu.ht1.jpg)

Now I'm wondering what effect not jumpering would have on the bike's operation, as if the BMU was simply removed from the relay box.

Post by: TimTyler on March 17, 2016, 03:13:26 PM: I like that form factor. Easy to drill and the rubber grommet seals nicely. Same as my four rear turn signals. Maybe I'll get some red ones (http://amzn.to/1MbCeMN).

With the LED's I got I found that positioning them so the etched lines on the face are vertical provides the widest, most visible beam pattern.

Post by: TimTyler on March 17, 2016, 04:20:02 PM: Just took a look at the wiring diagram and, duh, without jumpering the socket, power will not be delivered to the tail and brake light.
Title: Re: Want to replace light bulbs with LED's
Post by: johnny on March 17, 2016, 06:51:54 PM: greetings...

the ones you mentioned in reply #13 are 2 wire... tail only...

Post by: TimTyler on May 03, 2016, 11:37:51 AM: So, Johnny, are your new LED's as bright as you expected?

I've been told my little turn signal LED's are hard to see in the daytime, so I've supplemented them with larger LED's.
Title: Re: Want to replace light bulbs with LED's
Post by: johnny on May 03, 2016, 01:44:51 PM: i can say this...

when wired to the bed of my truck they are brighter than wired to the bung of my moto..

so im thinking i need fatter wires on the moto...

Post by: gag1025 on May 16, 2016, 08:07:44 AM: I prefer LED bulbs over 1157 because of the fact that in the US they are eventually going to do away with incandescent bulbs and you will be forced to use LED's. I have them in my home (got a great deal on price through my power company-Duke Energy- on all the different types I needed). Not a factor on the bikes or the cars and trucks, but in the house the operating cost is cheaper and they will last much, much longer that a standard incandescent bulb. Plus in the house they are much brighter.
