Everything ok, I recommend for CB500 - fits perfectly. The heat sink provides adequate cooling, the factory one did not have it and there was a problem.
About a year ago I installed a colleague in a Honda CB500 - probably 1998.To this day he does not complain. Recently another colleague had a charging problem (also CB500, 1999) and asked for advice (the previous regulator - "more branded", read much more expensive - seemed to overcharge the battery [colleague's opinion, I did not check]. It turned out that everything was OK, the one evaluated remained stock).
In both cases, the spacing of the mounting holes did not fit very well, but it's 0.6 mm max - just "lick" the housing with a suitable conifer.
There could be a little more charging voltage (original :14.5 V, evaluated : 14.17 and 14, 22 V - two copies).
If someone "embraces currents" and would like to check the reg. "dry", just like the "classic" ones. - regulated power supply, bulb voltmeter - then you may be strongly surprised. But after installation in the motorcycle everything OK. Probably some "more advanced" technology (perhaps - it's a little undervoltage is also not always so ?) Considering the price / quality ratio - I recommend. In general - in Hondas (at least of these vintages) you need to take care of the charging installation. Most often the problems begin at the connectors of the 3 yellow cables from the alternator. Corrosion, oxidation, increase in resistance, overheating, the rectifier-regulator begins to overheat, the internal electronics fall apart, no longer regulate the voltage and we have a "bubble" from the battery. It is worth checking these areas carefully.
With Hondas (CB500, Transalp) I have done a little more than 80 kkm, and also a little at colleagues' repair.
CPI Popcorn 70 2003. very good bulbs in the price-quality ratio, definitely met my exorbitant expectations, 6 leds give a very strong light, white light that can be seen from a long distance even in the day. Banal even installation. Shipping immediately! I highly recommend these bulbs. Gmoto never disappoints its customers!
Honda CB 500 S, 1999.
Before replacement charging only above 3000 rpm at slow 12.3 volts without load, after replacement 14.3 volts after load 14.1-14 volts (you would have to check the battery and the pradnic-alternator itself before you proceed with the replacement)
In summary - good purchase quality / price
I recommend
the product was received in good time, the product was well packaged, the product is mounted in place of the original. it works correctly for now. best value for money for this type of bulb!
I am pleasantly surprised by the amount of light generated from such a small source, in my scooter now the position " can do for daytime". I recommend the purchase and the seller this is not the first time I am satisfied with my purchases.
After ordering the product, I did not expect to get it earlier than it was described, I got the product 1 earlier than the scheduled delivery, the product well protected in the shipment, it works flawlessly :)
