#1157 vs #1034 Tail/Brakelight - SOHC/4 Owners Club
Jul 7, 2010 · Tonight I tested both bulbs with my ammeter and here are the results. 1157 tail = 0.55A 1157 stop = 1.82A 1034 tail = 0.55A 1034 stop = 1.58A So, both tail filaments draw the same amount of current, and appear almost equally bright to my eye. The 1034 brake filament does draw less current, and appears dimmer. The brake light is only on a tenth ...
Turn signals not working on 1972 CB750, 1034 vs 1073 bulbs. 1073 …
May 26, 2011 · So far Ive found a few postings mention the problem when replacing the stock 1034/1073 bulbs with higher wattage 1157/1156 auto replacements. I've also found that 1034 are dual element bulbs for the front signals and 1073 are single element bulbs for the rear signals. All 4 of my turn signals are 1073. Does this make sense for this bike?
Upgrading The Charging System on a CB550 - SOHC/4 Owners Club
Feb 13, 2010 · Install a #1034 tail bulb, as it was the original type (today's #1157 non-Stanley bulbs use considerably more current). Disconnect the front running lamps in the turn signals, that can help. All the little things together make a significant difference!
Ignition Analysis: Honda's coils
Oct 31, 2008 · On any SOHC4, you could use the Dyna 5-ohm coils, straight swap. On a 750, you could use the 3-ohm coils and HM ignition, but with the Resistor Pack. On a 500/550, you can also use this 3-ohm combo, but only if the headlight is near stock wattage and the taillite is a 1034 bulb, or it will start running out of amps.
Turn Signal electrical phantom...help needed - SOHC/4 Owners Club
Apr 13, 2010 · #3 - Original flashers were balanced for the original bulb wattage. 1034/1073, NOT 1157/1156. #4 - Flash signal is on Orange and Light blue wires, both front and rear. Front run light power is on Orange/white and Light Blue/white. #5 - somewhere in the forum archives I posted a flasher terminal pin code chart.
What flasher bulbs.. in my cb550k1
Jul 21, 2008 · however.. the bulb i pulled out of there was a stanley 1129 and after a little googling i found it to be a 6V bulb.. not a 12. of course it was blown. I have a feeling that 12v is probably the correct bulb but I'm looking for someone to tell me that owns one. Thanks in advance!

Jul 16, 2009 · For max electrical performance, but with a strong headlight and coils, I still recommend the 1034 taillight bulb (stock) and a 50/60W halogen headlight, with Transistorized Ignition, a Resistor Pack, and Dyna 3-ohm coils. That's going to be my setup, as soon as I have time to stop building ignitions for everyone else, and work on my bike!
turn signal relay question - SOHC/4 Owners Club
Apr 29, 2012 · Re: turn signal relay question. « Reply #2 on: August 22, 2009, 07:14:35 am ». The stock ones are thermal type, like the little metal can ones that are often found in cars. These are quite voltage sensitive, and low battery volts will cause them to be erratic. Try a solid-state flasher (3 terminal is best, use all 3 wires) for a nice, crisp ...

Sep 3, 2017 · As already mentioned, 1157/1156 bulbs are the common replacement for the 1034/1073 originals. However, the wattage/load on the flasher is different, which changes the flash rate. The original flasher was balanced for the original bulbs.

Jul 25, 2008 · A classic example at SOHC4: using 3-ohm coils on a CB500/550. After 1 week of normal daily in-town riding, the battery voltage will drop to 12 volts or less. Throw in a halogen headlight and a #1157 taillite bulb (instead of the stock #1034), and it will be down to 11.5 volts and a very hot rectifier and alternator stator.
