Base does not have HID there are conversion kits and our vendor here
Automotive LED Replacement Bulbs & Lighting Upgrades sells both the kits and OEM replacement bulbs used for EX that have HIDs standard. They also have all the bulbs for the outside. If you contact Diode Dynamics and mention this forum your standard shipping is free. Many companies sell HID conversion kits some are good some are not. All HIDs use a High Voltage ballast so you need to be careful in installing them.
Biggest hint is the turn signals will need load resistors added to avoid Hyper Flash. Diode Dynamics sells them too.
Usually the base uses the Headlight as DRL and EX and EX with navigation have LED DRLs. The base when it uses the headlight as the DRL causes issues with LED upgrades. LED Headlights are now apparently illegal(see below)

. There have been postings on here with how to use LEDs as DRL using diodes and relays.
If you want to add Fog lights to your base look for part number
08V31-SZT-100B ($317.60 from
https://www.hondapartsnow.com) and you can follow these directions for installation
https://www.collegehillshonda.com/instructions/crz/2014/foglights.pdf. Kit contains everything you need including the stalk with switch. You can upgrade the fogs to LED prior to installation if you wished. Diode Dynamics now sells Full LED fog light replacements but you have to have the factory Housings switch etc to use them.
Diode Dynamics has this note about legality of LED headlights on their page not sure how any LEO or other legal entity will react and I plan on installing LED headlights anyway but we all should be aware of the legality. I hope that state inspections will not be an issue.
APPLICATION NOTICE: LED bulbs are legal in the USA for Fog Light use only. Not compliant with DOT / FMVSS108 and not street legal in the USA for Headlights. Legal for off-road use in ATV, snowmobile, and off-road racing use. International legality varies by country. Note: This usage regulation is not unique to Diode Dynamics bulbs. All LED bulbs from all brands, regardless of marketing claims, are prohibited from street use in halogen headlights in the USA.

Street Use of LED Bulbs
Diode Dynamics is suspending the sale of LED Headlight bulbs in the United States, due to federal regulations which restrict the use of replaceable light sources in headlamps. This restriction applies to all LED Headlight bulbs on the market. It is not unique to Diode Dynamics.
Our LED Headlight bulbs were designed and tested for effective photometric output, providing increased output with compliant beam patterns when installed in specific applications. However, the federal regulations do not include any provision for LED replacement headlamp bulbs. Therefore, it is not currently possible to certify any LED bulb for headlamp use.
The regulations are updated very rarely, with the last major revision occurring in 2007. However, we maintain hope that progress will be made so that advances in technology may be accommodated in the future. Newer technologies like LED lighting offer many potential benefits to consumers, which we believe should be incorporated into the regulations.
We apologize for any disappointment or frustration, and hope you will be able to find an alternate solution for your headlight needs. We are pleased to continue offering bulbs for other applications on your vehicle, as well as our highly-rated lamps and off road lighting products. Thank you for your understanding and support.
International customers may continue to find LED Headlight bulbs available in their market, based on local laws and regulations.
Guess I got lucky and ordered mine prior to their decision.
