This may be sort of a dumb question here, but I'll just throw it out since I'm close to considering it...

On my ES, the back-up light bulb is a 921 type (18W rating). I have looked in this forum and other places online, and saw that the M6 bulb is often used on the GS as a LED bulb in the high-beam housing, and is also rated at 18W. I'm wondering if an M6 bulb can be substituted for a 921 bulb. Thanks

 

Yes....M6 in reverse light....i did it a while back....still going strong.

 

Nice to hear that PHML

One more question... is Eurolite a good aftermarket lighting brand? I'm deciding myself on a set of M6 bulbs from either Eurolite or Polarg. I'm guessing that Polarg is a pretty popular choice for the GS owners here, hence must be a reliable brand

 

same here, m6 on mine and very good.

honeslty i never heard about eurolite before. since polarg has been so good on me, i never spend the time to look for more

 

I read Eurolite sucks....a few have blown up. Stick with polargs.

 

Finally got these Polarg bulbs after playing a game of tag with FedEx for almost a week. They're installed in the reverse-light application on my '01 ES, and with the cleared tailights as the main reflector, I think these bulbs really outshine my stock bulbs. The light output is much crisper, whiter and more refined, not like the scattered yellow lighting from the stock ones. Very satisfied with these bulbs

After pic.

Tailights with the new reverse lights turned on.

Since I don't have a tripod, I'm unable to show a clear pic of the reverse lights at nighttime, so this will have to suffice

 

I got M6 on my tail too...it's nice

 

very nice i always have superwhite for the reverse, so much clearer
