Hot start issues and Cheap LED 1157's

I know there's been lot's of talk about the 1157 LED bulb not worth the money, but I had to find out for myself. I purchased a pair of 32 LED 1157's for $12 on ebay to put them to the test.

Here's what I found...

They are bright-much more so than filament bulbs, but they are directional light. When I installed them, I noticed that they point slightly down so they didn't appear as bright as original bulbs so I bent one of the sockets up slightly. That made a lot of difference and I like the look: very bright circles of red light (I ordered red LED's) like two alien eyes looking at you.

So I just saved some watts by switching over to LED's.

Tonight I took the bike out to pick up some treats for my kids at the local mini mart. When I pulled in, a guy in a pickup following me said "Dam those lights are bright" so I know it is an improvement.

But wait, there's more...

The bike was fully warmed up when parked. When I started it up, I was ready for my normal routine of hot start issues (I'm nursing a 7 year old DieHard wet battery) but it fired right up.

Ok, so I was lucky, or was I...

I wanted to heat it up so I took it out on the interstate for a few miles then round some backroads on the way home (5 miles) keeping the RPM under 4k to put a load on the charging system. Just to make sure the engine was hot, I let it idle in the garage until the fan came on. I turned it off (fan continued to run) then on again and touched the starter button. It fired right up.

Conclusion: The LED bulbs save just enough wattage to let the ignition coils fire the plugs when hot. I always did have a hunch that when hot, the coils didn't get enough juice to start the bike.

Style and function for $12. I'll post some picts this week.

Thanks for the update - sounds like you got a great deal on a number of counts. Any idea what the bulbs run not-on-eBay?

Here's the bulb I used

I won a 2 pack, but this is the same bulb. I wasn't expecting much, but I'm satisfied with the results. There's no way it's better than the LED board, but it works.

You can purchase them in parts stores also. $10 or less.

I changed all the bulbs (except the headlight) with leds, which I bought from Superbrightleds.com...Changed also the blinker unit. 4 reasons for that:
1) they last longer
2) they are brighter
3) they are faster (they turn on and off instantly)
4) they pull less on the battery

I just installed some 1157 x 32s into the front turn signals. VERY bright, but I'm getting a fast blink on all four turn signals now. Anyone else have that problem?

It's a common problem with LED's. You need to replace the blinkers with heavy duty/ electronic blinkers.

Soooo, pull the LEDs and reinstall the original bulbs? Or pull the turn signals and reinstall something else, still using the LEDs?

Err... meant flasher unit rather than "blinker".

FOR REFERENCE ONLY
http://www.kmtparts.com/catalog.asp?...showprevnext=1

Pull the 2? on the bike and take em to an autoparts store - you need electronic or heavy duty. I think there's specifics here - I'm going by what others have said, not experience.
